Update on My-Ice-Cream
As most of you know, I Sous-Vide Process my Ice-Cream Base. I have been using 150f for 2 hours, but after doing some research and using science as my reference, I've decided to use 162℉ for about 70-80-Minutes. It takes about 35-40 minutes for the base to reach 160℉ (I used a probe), and the additional time is to pasteurize and cook and denature the proteins. Pastueration at 160f takes less than 10 secs. From what I have read, holding 162℉ for about 25-30 minutes improves the overall texture. The denaturation of proteins and their ability to hold on to more water makes the temp work well. Think about it for a moment; the more water that binds to the protein, means smaller ice crystals. This also improves whey protein foaming and emulsification. What does that mean? It means that the foam formation improves texture and helps the Ice-Cream hold on to air that increased during the churning, which we know is overrun. With this Time and Temperature, all the planets line up (smoother
