I do just that. I take a Minibull, the model with the tube so that it will run on alcohol indefinitely. It is tiny and fist inside another model of Minibull made out of a beer can. That one takes and oz or two of methanol which is fine for boiling 1-2 cups of water for coffee or hot chocolate. The Minibull is good for frying fish, baking coffee cake, simmering rice, etc. I don't cook on the LittlBug apart from boiling water. It can boil a lot of water fast so it is great for dehydrated meals and it works well in wind and rain. it would not be hard to cook with though if you committed to it. I would suggest some type of diffuser disk to temper the heat.
