A trick I did not learn in the boy scouts for cooking food in a rainstorm: A tin can braced by rocks so it can not tip over, about half full of gas, not safe but it burns for an hour and people get fed. I use this system for starting fires in the snow when the wood is encrusted with ice or after an all night soaking in the summer. You just have to be careful because if you tip over the can, you have a fireball as big as a VW.
