Maybe you should experiment with hexamine solid fuel tablets. Inexpensive, compact, and non-explosive. Good for boiling up a cup of tea or heating up canned food. For baking or bigger cooking tasks, BBQ charcoal is a better deal.

There are many brands (esbit, coghlans) etc.

Don't bother buying the little folding stove; you can make one out of a tin can or a couple of bricks or anything. Remember to use it in a well-ventilated location and on a non-flammable surface.
