Electric pressure cooker waterless baking will stick to the pan, put in tin foil will not stick to the pan.

Waterless baking is not absolutely waterless, just need a small amount of water, and keep the water as much as possible not to leak out during the heating process, if there is no this feature, may lead to a large amount of water vapor emissions out of the heating process, resulting in no water heating in the pot, the food paste off.
