Well, technically I call my dish Chicago Dog, and I created not one but two recipes for the May National Restaurant Association show in Chicago. The Hot Dog Espuma was inspired by Chef Rick Tramonto’s Foie Gras, substituting hot dogs for the goose liver. The Chicago Style Foam was inspired by Cucumber-Yogurt Espuma, but I substituted the toppings of a Chicago hot dog: neon green relish, yellow mustard, onion, tomato, kosher-style pickle, and hot sport peppers.

I served the savory pink Hot Dog espuma and acidic green Chicago Style foam on a crisp Jay’s potato chip with soft, torn poppy seed bun, finished with essential celery salt.

Both of the original recipes can be found in the iSi Recipe Database online. Plus on the iSi Recipe app, I’ve posted my recipe variations.

What do you pair with Hot Dog Espuma?

My mixologist colleague Cristiana DeLucca paired my Chicago Dog with her Strawberry Soda and Lemon Infused Whipped Cream. In my last post, I wrote that Cristiana prefers to pair drinks from finished food menus. But how?
“I start pairings by thinking about if I want a similar or contrasting experience,” says Cristiana, “But I’m always thinking about how flavors will taste together, and that includes textures and aroma.”

Why, but why, Hot Dog Espuma?

People really like hot dogs, even at the National Restaurant Association show. Despite food samples everywhere, visitors waited in long lines for hot dogs, from New York’s Nathan’s Famous and Chicago’s Vienna Beef.

Thanks to everyone who visited our booth. Below you’ll find our full menu. Next time I’ll  share details for your chance to win an iSi Culinary Ensemble.

The Meal that Changed the
Course of My Culinary Journey

by Chris Young, CEO of ChefSteps

I never expected to become a chef. And I don’t think I would have become one if it weren’t for a meal that I had in early 2003 at a small, relatively unknown (at the time) restaurant west of London called The Fat Duck. My meal began with foam, the famous liquid nitrogen-poached Green Tea Sour.

For those unfamiliar with this dish, I’ll describe the experience: My server Didier rolled an opulent guéridon across the small and humble dining room, parking it beside my table of one. On top of the oak wood cart was a cauldron of steel and glass filled to the brim with liquid nitrogen simmering at -320 °F; beside it was a whipping siphon, a set of silver soup spoons nested within a linen napkin, a muslin satchel tied with a bow, and a set of chilled plates. Didier picked up the whipping siphon, deftly inverting it to dispense a bite-sized dollop of dense white foam onto the bowl of a shallow spoon, and then with a practiced motion plunged it into the nitrogen, which erupted to a boil as it cryo-poached my sour. He flipped and basted it with the spoon for exactly eight seconds, before lifting it from the liquid nitrogen, dusting the glossy white puff with the satchel of matcha, and then served it to me on a chilled plate with the request that I enjoy it as a single bite.

And when I bit into it, the glossy surface shattered crisply, giving way to a cool and luscious mousse racing with the acidity of lime juice and the slight astringency of green tea. But the best part was the rush of fog that streamed from my nose, making me look a bit like a puffing dragon. This dish is both literally and figuratively very cool. From this one bite it was clear to me that this meal was going to be very different from any other that I had ever eaten.

But the nitro-poached lime sour wasn’t just about theatrics—Heston Blumenthal had crafted it for the purpose of really cleansing the palate. If you’ve ever had a glass of orange juice after brushing your teeth, then you know how awful the alkaline residue of the toothpaste can make food taste. The acidic lime juice serves to neutralize this alkaline residue, while the green tea adds astringent polyphenols that help cleanse the mouth, and a very small amount of vodka provides just enough alcohol to disperse oils and fats.

Of course aerating and poaching it in liquefied nitrogen added textural surprise and an element of fun and whimsy that so often is missing from fine dining restaurants. By the end of my meal there was no question that I had to work at The Fat Duck, with Heston Blumenthal, and I was lucky enough to do so for the next five years. One of the many things I learned from working there was that a talented chef could accomplish extraordinary things when empowered by scientific knowledge.

Like all scientific progress, there was a lot of failure along the way. That light and delicate green tea sour foam would constantly collapse if not served immediately; the result of alcohol that tends to thin the bubble walls until they are simply too delicate to survive the pull of gravity. This was a real problem, because the foam itself kept the liquid nitrogen from freezing more than a paper-thin shell at the surface. If the foam collapsed while it was being cryo-poached, the experience for the guest was more like a tongue stuck to a frozen flagpole, which is not a great way to begin a meal. The solution for near-flawless foam every time was to use a whipping siphon, a unique tool that with the squeeze of the trigger created fresh foam on demand.

Transforming Modern Cuisine

Whipping siphons, like those from iSi, became a fixture at The Fat Duck, as well as every other modernist restaurant. That’s because these tools afforded chefs a better way to manipulate foams that in turn create texture. And manipulating texture is something chefs are always doing, whether they realize it or not. Whipped cream is perhaps the best-known example of texture being transformed by edible foam. It’s simple to make—you just create a lot of small bubbles in cold cream. The whisk is the basic tool for this job, and it does the work in two ways: First, as the wires are whipped through the air and then into the liquid, each wire leaves a trail of bubbles in its wake. Second, the wires stretch and pull existing bubbles until they split into smaller bubbles, which expands the whipped cream and helps make the foam stable. Doing this, however, does eventually wear out your arm. A whipping siphon makes the job easy, but also works in an entirely different way: It uses gas pressure to force soluble gas (nitrous oxide for whipped cream) to dissolve into the cream. When the trigger of the siphon is squeezed, the pressure pushes the cold, gas-laden cream through a valve stem, and as the cream emerges, the surrounding pressure suddenly drops, causing the gas to burst out of the solution as an uncountable number of tiny bubbles that whip the cream. The advantage, aside from avoiding a sore arm, is the ability to create as much or as little fresh whipped cream as you need.


But these tools aren’t just for gourmet whipping cream, nor are they only useful for modernist chefs looking to push the boundaries of cuisine. At ChefSteps, a company I co-founded over two years ago to teach and inspire home chefs, we’ve got tons of amazing uses for whipping siphons (which I’ll tell you more about in my next post, along with a recipe or two), and in fact we offer a comprehensive online class for home cooks, all about the many diverse ways to use a siphon (iSi customers can get 50% off the Whipping Siphon class now through July 31st using this link to enroll). We get feedback every day from cooks who are learning and trying new things with this tool they’ve had sitting in the drawer for years. It’s validating feedback for an unintentional chef such as myself—people are having the same experience at home that I had at the Fat Duck all those years ago, and today at ChefSteps, tapping into the power of whipping siphons.

Deep Dish Espuma plus Pizza Foam?
Lemon Basil Soda with “Tomato as a Fruit” Foam?

Trust us, we’re professionals. We being award-winning mixologist Cristiana DeLucca, Team iSi and me. We’ll serve this menu and more at the National Restaurant Association show, starting Saturday in Chicago.

We’re challenged with serving food and drink at a show, an industry event attended by some of the best chefs from around the world, including Top Chef Master Rick Bayless, but also the biggest brands in the food business. How do we demonstrate what we can do in one delicious bite and one delightful sip?

One of the iconic dishes of Chicago is our unique pizza. My favorite is made only at one restaurant: Burt’s Place. You may have seen Anthony Bourdain eat there, when I took him to visit my friend and pizza master Burt Katz.

Deep Dish, my take on our hometown’s divisive pizza, will be crunchy foccacia bits, torn mozzarella, onion microgreens, fruity olive oil, seasoned by smoked salt, freshly ground black pepper, and a fresh schpritz of lemon, then finished with the Tomato Hollandaise from the iSi cookbook, A Culinary Journey.

The Tomato Hollandaise was created by the Michelin starred German chef Andreas Schweiger. His variation of the classic sauce does use yolks and butter, but he adds tomato purée, lending intense flavor, preserved for any season.

The rich yolks, silky butter, and tangy tomato echo the Italian method of cracking an egg over a pizza right before it’s slipped into a wood-fired oven. Cooked until the crust bubbles and nearly blackens, while the white barely sets. It’s a very different pizza from deep dish, which some say isn’t pizza at all, yet both are correctly eaten with knife and fork. While devising the show’s menu I thought this would elevate a familiar favorite for finer dining.

But what about fast food? Espumas are one thing, but what about the weird? Here I was inspired not only by chefs but a bit of magic. Every year the restaurant show wraps just as what’s now called Sweets & Snacks Expo, aka the Candy Show, kicks off. The Jelly Belly booth always offers their Harry Potter Bertie Bott’s Every Flavor and Bamboozled beans, with everything from Sausage to Moldy Cheese jelly beans.

So while Deep Dish Espuma is lovely, the Pizza Foam may be something else. I take the cookbook’s Parmesan Cheese Fondant, by chef Darren Ong of Singapore, then spike it with Chicago Deep Dish Pizza Pizzazz by my friends at The Spice House. It may be weird but practical too. One day for lunch I grabbed a slice, then the ubiquitous shakers of cheese, oregano, and crushed red peppers to shower them furiously. What if we could capture all that’s lost, and occasionally accidentally inhaled, in a fun pizza foam?

Our menu will change daily, all full of flavor, evocative and provocative, but above all, delicious and delightful, we hope.

Cristiana and I have worked together with iSi before. She prefers to pair from my food menu, but how does she do it? More on mixology next time.

I grew up in my family’s Chinese-American chop suey restaurants in Chicago. My first job, at the age of four, was folding pale jade green paper menus into long, clean thirds. Soon after, I started cooking, standing on a milk crate, watching over the deep fat fryer bubbling with lard, waiting for golden, crunchy egg rolls to surface. I rarely dipped into our house-made sweet-and-sour sauce, but understood how customers loved the cooling, tart contrast. I preferred the quietly fiery mustard, which we endangered ourselves to mix with Colman’s dry powder from the tin. Later I made my own family meals—fried rice a favorite—picking through our mise en place, cracking a fresh egg here, grabbing a handful of scallions there. From behind the bar, I’d pour ginger ale into hot tea, which drove my grandfather crazy. Working through weekends, holidays, and childhood, I swore to never work in restaurants again. I moved to Los Angeles, but never stopped cooking, especially since we had farmers’ markets all day, and endless, summery, southern California nights to entertain in our bungalow backyard. But after one LA evening out at a wine tasting, the food was so bad I told the shop owners I could do better, so I did. I paired French Champagne with classic gougeres and smoked salmon deviled eggs, plus retro rumaki and miniatures of our egg rolls. I started catering, and I was surprised how much I enjoyed cooking professionally again. Then I met Julia Child, while she was on book tour for the 40th anniversary edition of Mastering the Art of French Cooking. Inspired, I attended her alma mater, Le Cordon Bleu in Paris. After graduation, and many calls and letters, I staged at Alain Ducasse at the Hotel Plaza Athenee. In my wildest dreams I never imagined a restaurant kitchen or cooking could be like that. It was pristinely clean and air-conditioned, with caviar, foie gras, and white Alba truffles as plentiful as potatoes, carrots, and onions. Later that breathtaking year, I staged at El Bulli. I was amazed by not only my own rekindled wonder, but that of the cooks from around the world with whom I worked too. You must know by now that chef Ferran Adria opened the restaurant only six months per year, closing the other six months for what he called “the creativity.” But before it famously became the World’s Best Restaurant, they had no customers. Ferran and his brother Albert said they’d go days serving one table or two. So instead, they created. It was there that Ferran Adria himself discovered iSi.


iSi North America President and CEO Rick Agresta once told me that HQ was wondering why some unknown restaurant outside of a small Catalonian resort town was ordering so much product. So they went to see for themselves. In 1994, Ferran made his first espuma: “white bean foam with sea urchins: the first foam.” Ten years later when I apprenticed, it was space camp for cooks. We had liquid nitrogen, a centrifuge, and dozens of iSi whippers. Some had custom tip tubing to make the infamous “2 m of parmesan spaghetto,” a single, long translucent noodle of whey and agar. It was served plated with balsamic vinegar, lemon zest, and black pepper. I prepared this and another Parmigiano Reggiano dish with an Italian cook who worked for the Michelin three-starred chef Massimo Bottura in Modena. He always cursed what we did to his iconic, beloved hometown cheese. When I returned to Chicago, Lavazza introduced Ferran’s Èspesso Espresso at their downtown cafe, for the first time in the country. It is essentially espresso, cream, sugar, and gelatin, set and served in an iSi whipper.


Now as a food consultant and food journalist, my concerns consider not only the delicious but simplicity, sustainability, ethics, and nutrition too. I’ve since made Èspesso, adapting it to my own taste. So I choose ethically sourced cold brew coffee, pastured heavy cream, and real maple syrup, adding American breakfast flavor. Always recycling the chargers, of course. I may inject my American Èspesso into fluffy raised donut holes, occasionally with a shot of whiskey. While I hope to forever discover new child-like wonders, grown-up toys and tastes are sure fun too.


Ferran Adria’s Èspesso for Lavazza uses espresso. I use cold brew coffee concentrate because I prefer the smooth, chocolaty flavor, plus it’s easier, much easier. If you don’t have a cold brew coffee ratio or recipe you like, try mixing one part finely ground coffee to four parts water, then steep for 12 hours minimum. You do not need a cold brew coffee maker. Remember, this recipe uses the concentrate, not the diluted coffee. I do use both weight and volume, because sometimes it’s easier to use one over the other. Try to eyeball the half pouch of gelatin, and if you’re half a gram over or under that’s fine. You can substitute the maple syrup with sugar, use more or to taste. This is a very forgiving recipe.

330 g cold brew coffee concentrate
0.5 pouch (3.5 g) Knox unflavored gelatin
50 g maple syrup
119 g pastured heavy cream

Preparation: Pour 50 ml of cold coffee into an iSi Flex-it 1000-ml (4 cups) measuring cup. Sprinkle half a pouch of Knox unflavored gelatin over it. Let stand for one minute. Pour 50 ml of coffee into Flex-it 250-ml (1 cup) measuring cup. Microwave to boiling. Carefully pour boiling coffee into cold coffee and gelatin mixture. Use an iSi silicone spatula to stir until gelatin dissolves completely. Add remaining coffee, syrup, and cream, and then stir again. Pour mixture through an iSi Funnel & Sieve into a 0.5-L (~17 fl. oz.) iSi whipper. If using a Thermo Whip, chill empty whipper thoroughly first. Charge with one iSi cream charger then shake well. Chill one hour minimum to set. Test for desired consistency. Shake further if firmer texture preferred. Serve.

Serving Suggestion: Dispense to espresso cups, top with whipped cream, sprinkle with cocoa powder, then serve. Or fill yeast-raised donut holes using iSi short 5-mm injector tip, then serve. Optionally add a shot of whiskey or other spirit to whipper before charging. Take care to only fill whipper to maximum fill line. Keep refrigerated.

Stay Tuned! Louisa will be popping up on periodically with updates and recipes to help you make the most of your iSi Whipper System, so stay tuned!

Mastering the Art and Science of Flavor Extraction with Dave Arnold

It was August 2010. Dave Arnold, a friend and former colleague, was very excited to show me a culinary technique he’d been working on. At the time, I was iSi’s culinary director and had been encouraging Dave to play around with the whippers to see if he could come up with some new applications beyond creams and foams. It was through his experimentation that Dave, a master tinkerer, cocktail savant and culinary innovator, came to discover the exciting potential of rapid infusion – extracting the flavor of a solid into a liquid or infusing a solid with the flavor of a liquid, or both – using an affordable, handheld device.

liquid_intelligence_newThe discovery of this application opened the doors for flavor in ways that was not possible before for those without access to expensive vacuum machines and the know-how to properly execute the technique. In subsequent years, Dave has demonstrated how to use iSi Gourmet Whip Plus for rapid infusion to some of the most respected chefs and mixologists in the industry and in front of packed houses at various high-profile events and conferences around the world. But with the launch of his new book, Liquid Intelligence: The Art and Science of the Perfect Cocktail, the technique is now accessible for everyone.

In the book, Dave breaks down just about every element of the cocktail and how to improve on taste, texture, appearance, etc. – from traditional drinks to adaptations using modern techniques. He devotes an entire chapter to “Rapid Infusion, Shifting Pressure” where he explains the basic process of rapid nitrous infusion and the potential benefits of using a whipper and nitrous oxide (N2O) – a water/ethanol/fat-soluble, colorless, slightly sweet-tasting gas – versus more traditional long-term infusion methods.

Rapid infusions made using an iSi whipper with N2O tend to extract less bitter, spicy, and tannic notes as compared to traditional extraction methods that rely on heat, time, or a combination of both. For cocktails, rapid infusion allows for more of the pleasant notes to shine. Imagine a jalapeno infused vodka with all the bright flavor and aroma of fresh jalapenos with less spiciness or an aromatic coffee liquor made from coffee beans with less bitterness and less tannic notes than one that steeped over an extended period of time.

In addition to being an entertaining and educational read, the book contains several recipes for infusions, bitters, tinctures, and finished cocktails using these rapidly-infused ingredients.

While the approach may seem thoroughly modern, the end goal for using the technique is simply to make a better tasting, better looking cocktail. By reading through Dave’s recipe for turmeric infused gin you’ll get a sense of the basic method. He explains why turmeric is a good choice because “it’s porous, aromatic, colorful, and flavorful, the four characteristics you should look for in your solid infusion ingredient.” Gin provides a clear base that will complement the flavor and absorb the color and flavor of the brightly hued turmeric well.



500 milliliters Plymouth gin, room temperature
100 grams fresh turmeric thinly sliced into disks, room temperature (Tip: To avoid staining, wear rubber gloves when handling and cover surfaces)
.5 liter iSi Gourmet Whip Plus
2 iSi Cream (N2O) Chargers
Add prepared turmeric to the whipper, then gin. Screw the head onto the whipper and charge using one cream charger. Swirl the whipper for a few seconds to agitate and then charge again using the second cream charger. Swirl the whipper again. As you swirl, the gas will dissolve into the liquid, and the pressure inside the whipper will drop forcing the gin and nitrous oxide solution into the turmeric. After 2 ½ minutes, hold a container over the nozzle and place the whipper over a bowl to catch any escaping liquid. Point the nozzle straight up and vent the gas quickly by fully depressing the lever. As you vent, the nitrous expands and bubbles out of the solution, forcing turmeric-flavored gin out of the turmeric and back into the rest of the gin, completing the infusion. Once all the gas has released, unscrew the whipper and allow bubbling action to subside before straining. Allow infusion to rest for about 10 minutes before using for maximum flavor. Store chilled for up to one week.




A variation on a lime sour using the brightly hued turmeric infusion.
Makes one 5 1/3 ounce drink
2 ounces (60 ml) Rapid Infused Turmeric Gin
¾ ounces (22.5 ml) freshly strained lime juice
Flat ¾ ounces (20 ml) simple syrup
3 drops saline solution or a generous pinch of salt
1-2 dashes Rapid Infused Orange Bitters, or commercial variety Orange Bitter
Combine ingredients in a cocktail shaker. Add ice, shake, and strain into a chilled coupe glass.

More Rapid Infusion Tips from Dave:

  • Solids for rapid infusion must be porous. Most plant products meet this criterion. Flavorful options include fresh herbs, citrus zest, ginger, lemongrass, peppers/chilies, cocoa nibs, coffee beans, etc.
  • With the exception of fresh herbs which can bruise easily, finely cut up or grate solids to maximize surface area and expose pores to the liquid.
  • Pay attention to the solid-to-liquid ratio and infusion times. Rapid infusions typically take more solids than traditional infusion methods and happen so fast that even 15 seconds can make a difference in flavor.
  • Unless you’re making a bitter where bitterness is a desired, use room temperature liquids and solids. Infusions using cold ingredients produce less vibrant results.
  • Consistency is key. Always measure out your ingredients, set a timer, use the right sized whipper, and the right number of chargers for the recipe for consistent results.
  • The process of venting is what generates flavor-extracting bubbles. The faster you vent the gas, the stronger the bubbling action. The more bubbling action, the more active your extraction.
  • Unless the recipe instructs you to do so, don’t strain the mixture right away after venting. Allow bubbles to subside. Remember, active bubbles mean that flavor extraction is still happening.

On occasion, small particles from the solid may clog the value system and the whipper may stop venting properly. To avoid this, let solids settle to the bottom of the whipper a bit before venting and always point the nozzle straight up. If you do get a clog, try pumping the handle to dislodge the clog. This Fall, iSi North America will launch a newly engineered Rapid Infusion Tool that safeguards against clogging and allows for a more streamlined venting process. This attachment will be sold separately as an accessory and should only be used with the iSi Gourmet Whip Plus.

A Quick Introduction

Our President & CEO, Rick Agresta (shown below) was one of few influential  invitees to the MOFAD (Museum of Food & Drink) Spring Dinner Benefit just a few weeks ago in Long Island City, and was kind enough to share his recount of the inspirational evening created by Dave Arnold and Peter Kim of MOFAD — along with top-notch respected chefs including Wylie Dufresne, Michael Anthony, Marcus Samuelsson, plus many more of New York’s “Best of the Best” committed to the advancement, exploration, discovery and documentation of the science of food.

MOFAD was founded years ago by the culinary wizard and long-time iSi friend  Dave Arnold, and is working to build  a first-of-its-kind food museum in New York City – with exhibits you can actually eat. It reminds us a bit of Jennifer Rubell’s edible exhibits, but on a more permanent scale. Dave’s vision is expansive, long-term, and of course – unique. Dave’s constant dedication and exploration of the “way things work” and how he can make  them more useful, productive, or creative continues to set him apart from the “norm” in every way.

We hope you enjoy the descriptive storytelling though the eyes of iSi’s own CEO, who attended the event and clearly enjoyed the entire evening of surprise, delight, and culinary wonder.

I had the pleasure of attending the Museum of Food and Drink Spring Benefit Dinner at the very cool Foundry event space underneath the 59th Street Bridge. In Long Island City, Queens. As in the Simon and Garfunkel song about the bridge, several hundred guests and I were “feeling groovy” as we were served innovative dishes from the imagination of a star studded group of chefs. This was all in service of a great cause, the creation of the first museum devoted exclusively to food and drink and the culinary arts, science and engineering that help bring these essentials of life to us, ranging from mass production to local supply, from our supermarkets to the finest restaurants.

The Challenge

Each chef was challenged to create an entirely new recipe in response to a theme thought up by Peter Kim, executive Director, and Dave Arnold, founder and lead enthusiast. To give you a taste for the challenge, consider Wylie Dufrense’ (WD-50) chicken liver spaetzle, radish, Cocoa nibs and pine conglomeration. This was in response to the Four Humors – Blood, yellow bile, black bile and Phlegm, an ancient world concept with the humors corresponding to the elements of air, fire, earth and water – all of which must be in balance for a healthy constitution. Wylie served a very balanced and tasty portion.

A challenge from the less distant past was given to Brooks Headley of Del Posto who created a Bomb Shelter Sandwich for the category of Food of Future Past. Franklin Becker (Little Beet) had a yummy take on what the native Americans might have really brought to the first Thanksgiving, a garden, forest and sea to table mix.

My personal favorite was the Rastafarian Ital Diet response from Nils Noren of the Marcus Samuelsson Group and Dave’s partner in culinary crime for years at the FCI. Nils made a Callaloo Soup with Dumplings and Coconut served with Tamarind Ginger Soup. He labored with actual coconuts instead of buying pre-processed ingredients. As he wrote in the program ” Because the body is viewed as sacred, Rastafarians value fresh, unadulterated food.”

My opinion: fresh and delicious! Just the way food should taste as the fresh seasonal foods of Spring transition into early Summer in early May.

Evoking Creativity in Food

The final two dishes brought us closer to the present. Michael Anthony of Gramercy Tavern made a TV dinner of Salisbury steak, Mac and cheese and a mix of carrots and peas. This was served in the traditional Swanson style TV food tray with a compartmentalized base and a cardboard cover held in place by crimped aluminum. Dominique Ansel, chef of his self named Bakery, was asked to create a dessert for Food on the Battlefield. His “rations” for us culinary soldiers was an Apple pie care package where the ingredients were delivered to our table in specially sealed containers we had to peal back, tear and unscrew. We were amply rewarded for finishing that battle.

The crowd was a great mix of the many kinds of people and functions in the culinary culture of Greater New York. The media was also there in force and my table alone included a creative bunch from Food & Wine, Popular Science and Grub Street.

2014 is an exciting year for iSi as they celebrate “50 Years of Inspiring Food” and the establishment of the iSi brand. The iSi story is an exciting one to tell, which was proudly expressed throughout yet another stunning Booth at the 2014 International Home & Housewares Show (IHHS) in Chicago.

Several “back by popular demand” products were introduced, reinforcing the history of iSi’s inspiration, experience, innovation and creativity in cuisine.


New Products Showcased (Available Fall, 2014)

The iSi Sodamaker Classic was the most awe-inspiring new product on display, captivating visitors at first glance with its Mad Men-esque antique/retro design. Although the iSi Sodamaker Classic looks like a mesh seltzer collectible on the outside, there’s new technology within, most notably a lightweight high-pressure resistant BPA-free PET bottle, and an advanced stainless-steel riser tube which produces a gentle, even flow of fresh soda water, every time.

Also on the new product podium:  iSi’s hip & redesigned lever-handled iSi Dessert Whip Plus and iSi Dessert Whip Mini. Both products feature fun & playful “zebra-patterned” black or white die-cut, removable silicone sleeve, providing the user with a more comfortable grip on the Whipper (and, adding a trendy-looking aesthetic!). This classic favorite has also been modified from its original aluminum bottle to a new dishwasher-safe stainless steel bottle. The clever & creative look of this product alone takes iSi to the next level, which I like to call “iSi 2.0”.

And to put iSi’s products to use, the new Culinary Inspirations cookbook provides a wealth of inspiring new recipes for the professional and home chef alike. Each day, I served a variety of food and beverage recipes from the book to let customers taste a bite of iSi inspiration for themselves!

Over the last few years, our iSi Booth has become exceedingly popular, considered as a “must visit” Booth at the IHHS Show. Our daily menu of innovative iSi food and drink recipes attracted several customers and friends, including Top Chef Masters winner and Celebrity Chef Chris Cosentino, PolyScience President (and inventor) Philip Preston, and Chef José Andrés.

El Bulli’s Ferran Adrià was in town all week, using iSi Whippers at Press events around Chicago, and as homage, our menu was crafted with a variety of simplified modern recipes that home chefs can make, too.

An Homage to iSi’s History

This was my fifth year as iSi’s show chef, and incidentally Adria’s twentieth anniversary in discovering the technique of making iSi espumas, but iSi’s 149th year. That’s right; the company was originally founded by Karl Fischer-Pochtler in 1865, a fact literally engraved at the top of the new iSi Sodamaker Classic – see below.

 iSi's rich historys spans back to 1865, when our Founder, Carol Pochtler began producing siphons. The company is in it's sixth generation, now in the hands of the innovative Mag. Christian C. Pochtler Chairman & CEO of the iSi Group

For my Edible Espresso 2014 Edition, I flash froze espresso cream (Kalona Super Natural whipping cream and Monin Espresso syrup) on a PolyScience Anti-Griddle, and sandwiched the frozen espresso bites between local Bridgeport Bakery doughnut holes. It was coffee and donuts in one bite – an adult afternoon snack!

The iSi Gourmet Whip: More Than Just Whipped Cream

Now that we’ve covered all you need to know on making fresh whipped cream in your iSi Whippers, let’s explore some other inspirational techniques that will take you beyond traditional whipped cream. It’s time to experiment and have some fun – if you can dream it up, you can whip it up!

Important: We only endorse using the iSi Gourmet Whip for these techniques, because it’s the most versatile product we offer, and it’s specially designed to handle all of the “beyond whipped cream” applications we’ll talk about today.

Flavor Injections – iSi Injector Tips

You already know and love your iSi Gourmet Whip. You’ve tried endless recipes for foams, espumas, batters, and just need that extra “umph” to take your culinary creations to the next level. iSi Injector Tips are an inexpensive attachment for your iSi Gourmet Whip which multiply the versatility of this already marvelous tool. Just attach an Injector tip in place of the decorator tip, and you’ve opened up a whole new world of possibilities.

Quickly inject flavor, brines or marinades into proteins like chicken, turkey or pork. The pressure from the iSi cream charger will do all the work.

To satisfy your sweet-tooth, use the iSi Injector Tip attachment to fill pastries like donut holes or muffins with flavored cream – or even “espesso” (espresso-flavored foam created by the great Ferran Adrià)!

Use the shorter Tips to decorate donuts with a mouthwatering chocolate drizzle, or when you’re working with strong flavors that just need a “touch” of iSi magic. Chef Louisa Chu of Chicago recently created a zesty Chive Emulsion – just a few small drops brought the perfect bit of “bite” to top off Roasted Potato Foam on a Roast Beef Crostini.

Made of 100% stainless steel, iSi Injector Tips are a great addition to a product you already have in your kitchen – or, if you don’t already own an iSi Gourmet Whip, maybe they’ll inspire you to add one to your toolkit just so you can inject, decorate, and stuff away! Plus, they’re dishwasher-safe. Just be sure to clean them between uses.

Here’s a great recipe for Tabasco-Maple Brined Fried Chicken from our friend Chef Chris Cosentino of Incanto in San Francisco. It’s also featured in our cookbook: A Culinary Journey.


Tabasco-Maple Brine:
Ingredients for 1/2 pint (.25 liter) iSi Gourmet Whip using an iSi Injector Tip
1 iSi cream charger
1/2 cup maple syrup
1/2 cup Tabasco or other hot sauce
1/2 tablespoon lemon juice
1 teaspoons kosher salt

Fried Chicken:
4 chicken legs
Tabasco-Maple Brine (see recipe above)
Buttermilk, for soaking
Seasoned flour, for dredging
Vegetable oil, for deep-frying

Combine all ingredients for brine until dissolved. Transfer 1 cup of the brine to a 1/2 pint iSi Gourmet Whip. Charge with one iSi cream charger and shake well. Screw on a long iSi Injector Tip needle. Hold Whipper with Tip pointed downward and inject chicken with brine. When complete, place chicken in a bowl and cover with buttermilk. Refrigerate overnight.

In a deep, heavy bottomed skillet or electric fryer, heat oil to 350°F, using a thermometer to keep track of the temperature.

Drain chicken and dredge in seasoned flour, shaking off the excess.

Working in small batches (to avoid a drastic temperature fluctuations in preheated oil), fry chicken until golden brown, about 10 to 12 minutes per side. The internal temperature of the chicken should reach at least 180°F.
Drain chicken on a rack placed over a sheet pan. Cover loosely with foil to keep the skin crisp while keeping the chicken warm.

Carbonation – iSi Soda Chargers (CO2)

Did you know that your iSi Gourmet Whip can also carbonate water (or, any liquid) – and also create fizzy fruits? The same (CO2) iSi soda chargers that you use in your iSi Soda Siphon can be used interchangeably in the iSi Gourmet Whip. Just be careful not to carbonate anything cream or milk-based (carbonation and cream don’t mix) – but anything else is yours to bubble up!

Carbonation adds zing and zip, and lightens flavors on the palate. Fizz up pure green teas or seasonal fruit juices. Or add all-natural Monin or homemade syrups to water to create your own artisanal, hand-made soda. Add a bit of bubbly to cocktails and wine. While it’s still cold outside, try sparkling mulled hard cider! We like Jill Houk’s newly released Complete Soda Making Book, featuring 100 all-natural handmade soda recipes – right now, we’re stuck on the homemade root beer, but we’ll leave the experimenting up to you.

To take your carbonation experiments to the next level, consider carbonating fruit in your iSi Gourmet Whip. Imagine orange slices, watermelon chunks, strawberries, raspberries, grapes, or even cucumber with a fizzy “love at first bite”. Why carbonate fruits? Why not! Imagine the difference between a glass of still water and soda water on your tastebuds. Soda water is more crisp, refreshing, and leaves a tingling sensation in your mouth. Plus it’s unique, fun, and an easy way to add some pizzazz to your next dinner party (and, of course – impress your guests with your modern cuisine skills)!

For best results, select fresh, juicy seasonal fruits (or, even vegetables). Ingredients with high water content work best (remember, it’s the water in the fruit that’s actually carbonating to make the crispy bubbles). Juicy pears, grapes, pomegranate seeds and ripe strawberries are some of our favorite ingredients for this technique.
Make sure to peel your fruit first and cut it into bite-sized pieces. If you’re using pomegranates, carbonate only the seeds.

For this technique, fill your Gourmet Whip bottle with the ingredient you want to carbonate. Screw on the head securely, and then charge with one iSi soda charger. Rotate/shake the bottle around a bit to mix the gas into the fruit. This process literally happens overnight – so make sure to chill in the fridge overnight for best results.

When you’re ready to serve, press the lever down to release all the gas from the bottle. Now the Whipper is de-pressurized, so you can unscrew the head. It’s important to serve your fizzy fruit immediately. This makes for a simple and fun garnish – drop into cocktails for an unexpected little surprise, or enjoy the twinkle of carbonated grapes one by one.

Batters – iSi Soda Chargers (CO2)

Whether you’re making pancakes or crispy tempura, using your iSi Gourmet Whip to aerate the batter makes it better. In the case of pancakes or waffles, you’ll see that they’re noticeably lighter and fluffier than a traditional preparation – and, as an added benefit you’ll get more yield from your batter since the tiny bubbles that are fluffing your food up take up extra space in the batter mixture.

In the case of tempura, you’ll notice an undeniably crispier, crunchier crust. We recently attended a cooking demonstration with Chef Richard Blais and the James Beard Foundation at Sur la Table in Chicago, where Chef Blais said he uses iSi soda chargers to aerate batter for his famously delicious onion rings in all of his restaurants – because they don’t get soggy as quickly, and have a crispier crust. Take it from us, or from the pros – this is a technique to try.

The trick to great tempura is keeping the batter chilled and carbonated, both which create a final dish that’s delicate and crisp -not doughy. With your iSi Gourmet Whip, you’ll make tempura like a master in no time. Here’s a simple tempura recipe to start with, although you can aerate any of your favorite batters (just make sure to run the batter through a fine mesh sieve – or the iSi Funnel & Sieve to avoid any particles getting stuck in the nozzle of your Whipper).

Tempura Batter Recipe
Ingredients for a 1 Pint iSi Gourmet Whip:
1 cup cold water
1 cup all-purpose or rice flour
1/4 teaspoon salt


1) Pour water into a large bowl. In another bowl whisk together flour and salt. Sprinkle flour mixture over water then barely whisk the batter. There will be lumps – don’t worry, this is normal!

2) Strain through a fine mesh sieve, or the iSi Funnel & Sieve

3) Pour the smooth batter into your iSi Gourmet Whip up to the indicated fill line

4) Screw on one iSi soda charger. Shake vigorously about 5 times

Test your batter. It should look like fizzy, soft whipped cream. Dip lightly floured pieces of seafood, veggies or tofu immediately, or you can let the batter chill in your fridge until you’re ready to fry.

Preheat your oil to 375°F and fry battered pieces until they are a light golden color. Sprinkle with salt while still hot – serve and enjoy immediately.

Welcome to light & crispy tempura – made the iSi way!

Now, let’s talk about fluffy pancakes (and waffles, too!)

1) Prepare your favorite pancake/waffle recipe, or pre-packaged mixture. Pour the batter through a fine sieve (or iSi Funnel & Sieve) into your Gourmet Whip, up to the indicated fill line

2) Screw on the iSi Whipper head, and charge with an iSi soda charger

3) Dispense batter directly onto hot griddle until golden brown

Voila! Fluffy pancakes/waffles served!

Tip: you can keep any unused batter in the fridge for up to 5 days.

Thanks for joining us in exploring some fun techniques beyond whipped cream! Remember, we also have a wealth of recipes in our online database:

Next week, we’ll get into the science behind foams and infusions using iSi Whippers, so stay tuned!


Welcome to Whipped Cream!

Why use canned whipped cream when you can get more flavorful, healthy, and signature results – just by using an iSi Whipper with an iSi cream charger?

There’s nothing better than billows of sweet, indulgent whipped cream on desserts and coffee drinks… unless it’s freshly made whipped cream that can be flavored with all sorts of other delicious ingredients, from flavored syrups & extracts to cocoa powder. It’s the kind of over-the-top garnish that creates craveability and premium appeal for any dessert-lover, and using the iSi Culinary System (iSi Whippers + iSi cream chargers) makes it easy to make & store, too.

Cream of the Crop
The appeal of fluffy, delicious homemade whipped cream can turn a standard dessert into an irresistible signature dish that will taste as wonderful as it looks!
• Transform pre-purchased, fully prepared desserts like cakes, pie, brownies and more into must-have signature desserts
• Build decadent sundaes and other ice cream confections that will appeal to anyone on your guest list
• Garnish floats, milkshakes, and malts that no one could turn down
• Create specialty coffee toppings and creamy, hot after-dinner drinks to enjoy as a treat for yourself, or with guests at your next dinner party

But wait – iSi Whippers are more than just fresh whipped cream- they are:
• More sanitary than consistently pressing your finger on the tip of an aerosol can
• Hygienic, with a controlled, air-tight system
• High-yield: 5 times what you put in (higher yield = lower cost per serving!)
• Long-lasting: Cream stays fresh for up to 10 days when using fresh ingredients and storing in the refrigerator
• Refillable and environmentally-friendly
• Under Warranty for 2 Years
• Easy to use

Plus, professional, stainless steel iSi Whippers are:
• Dishwasher safe
• NSF certified; HACCP compliant (for restaurant/foodservice use, too!)

Versatility Matters
Replacing pre-made or canned whipped toppings with fresh whipped cream made in an iSi Whipper allows you to use ingredients you may already have on hand—not just heavy cream, but a whole pantryful of flavors—to create delicious desserts and much, much more, including:
• Light & fluffy whipped cream to top off coffee drinks
• An extra-special treat for indulgent tiramisu or chocolate mousse
• The most important ingredient in strawberry shortcake!
• A filling for donut holes (using iSi Injector tips)
• A topping for freshly made waffles with fruit compote

The versatility of whipped cream is another reason why we love it so much. You can also make it lowfat if you like, and cream is a great base for many sweet & tasty flavorings – you can flavor it in so many ways (sugars, syrups, powders). For us, it just doesn’t get any better than that. Whatever you decide, it’s sure to be delicious and fresh every single time.

The Sweet Stuff
To sweeten your fresh whipped cream, you can use either powdered sugar or regular granulated sugar (powdered sugar dissolves a bit faster). Honey, maple syrup, agave nectar or flavored syrups all work well too. If you’re looking for a lower-calorie alternative, you can use Splenda, Equal or any number of the many Stevia-based sweeteners available.
Monin, maker of gourmet flavors from France since 1912, offers natural syrups including many fun seasonal flavors.
Extracts offer you the ability to add flavor while controlling the amount and type of sweetener used. You can’t go wrong with pure vanilla extract – but other commonly available extracts on your supermarket shelves include almond, lemon, coffee, and rum- just to name a few.

Or, spice it up a bit! Try a savory whipped cream with smoked salt, chili powder, wasabi, or even horseradish to serve with savory dishes like braised short ribs or smoked salmon.

Making Whipped Cream in an iSi Whipper

All iSi Whippers make fresh whipped cream (makes sense – right?). To choose the best iSi Whipper for your needs, visit the products section of our website:

Choose either “Home Use” or “Professional Use” to get started, and you’re on your way to exploring the many varieties of iSi Whippers that you can add to your kitchen, based on the recipes you want to make.

So – let’s get started with making your own fresh whipped cream with an iSi Whipper:

1) First the cream. You can use any kind of heavy whipping cream. We like heavy whipping cream, and use it in most of our iSi recipes because of its lovely taste and texture.

2) Then add any sweeteners and flavorings. Again, use whatever you want: cane sugar, Stevia, honey, agave, maple syrup, or flavored syrups. Just make sure any sweetener is completely dissolved, or particles will clog the release valve of your iSi Whipper. If you prefer, you can also avoid any sweetener because you may find find the taste of cream sweet enough, especially when topping a rich drink or dessert.

3) Make sure to fill your iSi Whipper up no further than the maximum fill line etched on the outside of the bottle. You can also use a measuring cup, like our iSi Basics Flex~it ® flexible silicone measuring cups to pre-measure your ingredients for a half-pint, pint, or quart-sized iSi Whipper. This is an especially good idea when adding flavored syrups as you don’t want to pour in more liquid than the capacity stated on the iSi Whipper’s fill line.

4) Screw on 1 iSi cream charger and shake vigorously until the desired consistency is achieved, typically 3 to 5 times.

Now – test the consistency. Hold the bottle with the tip pointed straight down and press the lever to dispense.

And… voila! Fresh whipped cream! Time to taste your fresh creation!

Storing Your Whipped Cream
You can store the rest of your whipped cream in the refrigerator with the bottle on its side. Remove the decorator tip and wash it by hand, using the cleaning brush included in the original packaging. Remember to recycle your empty iSi cream charger – it’s made of recyclable steel. Your whipped cream will keep fresh and fluffy up to 10 days when stored in the refrigerator!
