My wonderful husband got me an isi gourmet whip for Christmas and I decided it was time to play. I had co2 cartridges and grapes so I made carbonated grapes as my second experiment (I made whipped cream the day after Christmas but I can’t post those pictures). The secret to carbonated is…owning an isi whipping syphon. That and cold. Cold allows Co2 to get into food on a molecular level. No cold, no fizz. You need to chill both the whip and the grapes completely. Then you need to put in 2 Co2 cartridges being sure to hold down the handle to expel gas after the 1st cartridge but not the second. This gets rid of the air at the top of the canister so that it is completely filled with Co2. The Co2 must now make it’s way into the fruit so you refrigerate the whole thing on it’s side. Grapes take 8-10 hours to carbonate and last about 10 minutes so serve immediately. Once we expelled the gas and pulled them from the canister they were sizzling and whistling with co2. They taste almost like fermented grapes. We paired them with some Pt. Reyes blue cheese, but we immediately thought…sangria!
The 19 hour sous vide octopus is a smashing success! We took out one of the yummy umami tentacles and simply sliced it over some lemon, sprinkled with paprika and chowed down. It is fantastic. Perfect texture! We also got out our sriracha and dabbed some on top because we thought it could use some heat. We have tons of ideas for this and we are having some friends over tomorrow to try our little experiment. Check out Wednesday for the update.
Today I made the first step towards spherical yogurt, an agitate bath. According to molecularrecipes.com I need to mix 7.5 grams of sodium agitate with 32ounces of water and blend with an immersion blender till completely dissolved. I chose a medium size square glass container for this partially so I could see what was going on better.
The first thing I discovered was that I need a better scale. Mine is a pain to zero and it doesn’t measure fractions of grams so I’m just guessing at 7.5 and hoping it doesn’t matter much.
The instructions say blending could take longer than you expect but it only took me 3 minutes, which of course made me wonder if I had done it correctly. Did i mention that I’m an artist not a scientist? The mixed agitate bath now has the texture of bubbly snot. I place the bath into my fridge for the requires 24 hours to allow the air bubbles to dissipate and hope for the best.
