iSi Soda Siphon Stories March 5, 2015

Back in my January Kitchen Tech column on bar tools, I briefly mentioned that certain restaurants are using liquid nitrogen to make frozen cocktails that resemble sorbets — a magic trick that for all intents and purposes is impossible to replicate at home. But when nitrogen comes together with oxygen to form nitrous oxide (N2O), the result is a gas with unique powers. Nitrous oxide can supercharge engines, work as a “laughing gas” anesthetic, and… create whipped cream, ultra-fluffy pancakes like the ones shown above, and super-crispy waffles. You can probably guess which of these applications I’m exploring in today’s Kitchen Tech.

The iSi Gourmet Whip Plus has made guest appearances in two prior Kitchen Tech columns: column 3 on pro-caliber modernist cookbooks, and last week’s column on carbonating tools. It is the only modern kitchen tool Ferran Adrià recommends to home cooks in The Family Meal, and made the top 5 tools recommended by Nathan Myhrvold’s Modernist Cuisine at Home (alongside sous vide water baths and pressure cookers, which Kitchen Tech has already covered).

Why hasn’t it received its own column before now? Because it typically needs to be used with something else in order to make a special product. So for this week’s Kitchen Tech, I’m going to show you how to make the lightest, crispiest waffles you’ve ever had by combining an iSi Whip with a Belgian Waffle Maker. Read on for all the details…

iSi Soda Siphon Stories February 25, 2015

I realized the other day that my first exposure to carbonation – the little carbon dioxide bubbles found in soda — came so early in life that I couldn’t possibly remember it. My kids will eventually say the same thing. Despite warning parents that sugary drinks are unhealthy, doctors still recommend fizzy ginger ale to settle kids’ upset stomachs, and no one’s likely to give up Pepsi, Coke, or Red Bull any time soon.

But carbonation isn’t just for sodas. It’s also the bubble power behind beer and champagne, as well as some avant garde culinary tricks that are both surprising and compelling. This week’s edition of Kitchen Tech looks at three different and affordable ways to bring carbonation to your drinks — and food (!) — at home.
