The only difference I can spot between the first and second time is that the first time I burned alot, let it boil over twice by accident, and it was just overall a much messier process than the second time I tried (when it DIDN'T work...)...


with that i'd say that you weren't using enough heat, boilovers mean heat, and lots of it, if it wasn't near as messy you obviously had to of used less heat (trying to stop the boilovers and whatnot before they even happened) or you used more ingredients the 2nd time, and thus need more heat, or seperate it into two batches or however many is needed.

also what kind of milk are you using? i would imagine whole milk would be the best, since it does have the highest fat content.. did you use two diffrent types durring both proccesses?
