Does everybody put the lid back on the Rice Cooker Plus when doing these cakes? I have watched the dvd from PC and for their cake they left the lid off. I have tried these cakes numorious times and they are always undone on the bottom...and if I try to cook them longer they tend to burn. Does anyone else have this problem? I would love to try one at my shows but am afraid it won't turn out and I'll just have a mess on my hands with a bunch of people looking at me.
