I bring an alcohol stove, the " Super Cat", for boiling water and generally use a fire to cook. That's an Ozark luxury though, it's legal most places here and done right doesn't hurt anything.

I've also brought a "Simmer Cat" which burns longer and not as hot as the Super Cat. That would work pretty good for cooking I'd think. Maybe not for frying fish, but good for some stuff, noodles and rice. They're easy to light, refill, and cool almost instantly when they run out, so they're a good choice for short trips.

If I'm going to be doing a lot of cooking and its wet out then I bring an old coleman exponent stove. I still have some fuel for it and it's a good stove.

All the newer ones you can buy all weigh more than a Super Cat stove, so I've not found any I feel the need to buy. I might make a wood burning stove though. I've seen some pretty nice designs for those and they'd work good here and would work good for cooking too.
