Thanks for the very well researched article on sous vide. Just want to make one correction. It is about Sous Vide Magic (SVM). I am a user of SVM for about a year and find it very useful for looking large quantity of food. It all depends on the size of the cooker. My SVM can control a cooker with 1800W heater. That means If I use a commercial rice cooker I can create a 14L size bath. The largest cooker I have used is a 24L cooker. It is very easy to use and does not need experimentation. Best of all, it saves lot of energy to cook too.
