Sous Vide Tempered Chocolate
I grew up in a cooking family and after getting a degree in Spanish and Anthropology, realized what I really wanted to do was to go to culinary school. After working in a NYC bank for a few years, I managed to get to culinary school and got my first jobs in NYC kitchens ...
Ingredients for 8
1 pound good chocolate, choped
Heat Anova Sous Vide Precision Cooker to 115ºF/46.1ºC.
Chop chocolate and seal it into zip-close plastic back using water immersion method to create vacuum. Place chocolate into water bath and let sit there until it is fully melted, about 5 minutes.
Take chocolate out and gently squish it around in the bag. Place bag back into hot water.
Reduce temperature setting to 81ºF/27.2 ºC. Add ice until you reach the cooler temperature, adding a cup or so at a time, then watching the effect so you don’t reduce the temperature too much. When water reaches 81ºF/27.2ºC, increase setting on the Anova Sous Vide Precision Cooker to 90ºF/32.2ºC. Water will come up to temperature pretty quickly. Let chocolate stay at this temperature for 5 minutes, taking back out every minute and gently squishing contents around (this distributes the crystals that keep the chocolate from getting streaky).
Finishing Step: Holding
After 5 minutes, remove the bag from the water. Dry bag completely, then snip the tiniest bit off the corner to use for piping or to empty into a bowl so you can dip things (strawberries?) into the chocolate. NOTE: I divided my pound of chocolate into 2 bags so I could test the tempered chocolate immediately and hold the tempered chocolate at 90ºF/32.2ºC for as long as I needed to use it—If you take all of it out and work with it, it starts cooling, which makes dipping tough. If you are just piping it, it is okay to take it out—it stays pretty pipe-able for a while, depending on room temperature. (I was working with the house at 78ºF/25.5ºC; results will differ in the winter when ambient temperature is likely to be cooler—just a word of caution.) Clean up is a snap—Use the bags like pastry bags, then toss.
