Aero Chocolate, Version 2

Aero Chocolate

My first attempt at making aero chocolate turned out pretty well, but I was not satisfied with the final texture, which I found to be too dense. As I was considering making it again, my copy of Ideas in Food: Great Recipes and Why They Work arrived, complete with the detailed aero chocolate recipe. A quick read revealed my mistakes: I had used N2O instead of CO2 to aerate the mixture, and had not allowed it to cool down to 52°C before dispensing it in the jars.

When we were invited to dinner this week and asked to bring dessert, I viewed the request as an opportunity to try the recipe again. If I corrected the errors the chocolate would turn out better, and if I failed it would still taste pretty good. I followed the same procedure as before, this time using 64% Manjari chocolate, and doubling the amount of blood orange oil from four to eight drops. I blended everything together and let it cool to 125°F. I charged the mixture with two CO2 canisters and piped it into smooth-walled eight-ounce mason jars.

I could see that the chocolate mixture was lighter and airier as I dispensed it. I capped the jars and put them in the freezer until it was time to serve. To remove the chocolate, I ran a thin spatula around the outside of the chocolate and slid it out in a solid cylinder. I plated it with some Mandarin orange syrup, a scoop of Meyer lemon ice cream, and a Meyer lemon crisp.

The texture was much better this time around, more mousse-like. The orange flavor was subtle but noticeable, a complement to the lemon from the ice cream and biscuit. What I loved most about this dessert was how easy it was to prepare. I think I’ll be keeping a supply of chocolate and CO2 canisters in the Belm Utility Research Kitchen from now on.

Just found your blog recently. I’m really enjoying digging through the archives. As I’m awaiting my Ideas in Food delivery, I had a couple of questions about your new iSi dispenser. Which model did you go with? I see the NO2 charges, but which CO2 charges are you using?

Thanks, Matt

I use the iSi Profi 1 quart size. Here’s the Amazon link:

iSi makes N2) and CO2 chargers; I get mine at the local Ace hardware store.

And thanks for reading!
