I made creme brule.
it was extremely easy. I used chefstep's recipe. You heat the cream to 70 degrees, mix with the egg yolks/sugar mixture, fill mason jars and cook at 80 degrees.
I did all with the Control Freak (small pot for the cream, large pot for the jar cooking) and it was, well, almost trivial. The results were delicious.
The recipe asks for a circulator for the jar cooking, but I the CF worked great.
