OK.. so I'm making a chocolate cream pie (basically a homemade chocolate pudding/custard poured into a prebaked pie crust and chilled). It's been in the fridge for about an hour now and still hasn't set up. Is there anything I can do? I thought I had cooked it over the stove long enough, it said not to let it boil, and it was plenty hot.... I hope I haven't ruined it!
