I have a few ceramic bowls that are oven, microwave, and dishwasher safe (I normally hand-wash them, though). I was looking at recipes for lemon curd and some of them recommended putting them in a metal bowl over a saucepan that has steaming water in it. Is it possible to instead use a ceramic bowl? It would not touch the water below, only along the rim of the saucepan.
Would this be bad for the bowl? I can deal with a few aesthetic scratches and scuffs on the side.
Will this take a lot longer to heat up?
