Littlesister – You have probably already considered this option but if not, I would suggest that for your indoor emergency cooking needs you get a small portable stove that uses butane canisters. Butane stores well and is, with proper ventilation, safe to use indoors (or in your lean-to) for cooking. I believe one standard butane canister will last for about 1+1/2 hours of cooking time. If you make something like soup or stew that has a high liquid content, you can bring it to a rolling boil, then put the hot covered pot directly into a thermal cooker (such as a Wonderbag, or similar item) to finish cooking by retained heat. That would stretch your butane fuel a good deal farther. Another option for indoor cooking, with proper ventilation, is a HERC-type oven that is fueled by candles.
