Ever since I heard of it, I have been in love with the concept of thermal cooking (also known as haybox cooking, among other things). Not only because of how energy efficient and environmentally friendly it is, but also because of its portability and convenience. Great for road trips, camping and pot lucks!

Trouble is, it seems like hardly anyone knows about them. I think they are pretty popular in some Asian cultures, but not in the western world.
So I'm starting this topic in the hope that there are some chowhounders out there who would like to share ideas and recipes for this wonderful way of cooking :)
