Here in the UK Coleman fuel/white gas is not so readily available as in the USA, I therefore dont use it.

Summer emergency cooking is a microwave oven worked from my PV system, or a small hotplate.

In winter I would use either a kerosene camp stove, which can be used indoors with care, or a charcoal grill, outside only of course.
At my mothers home I keep a second kerosene camp stove, and also a liard fire box, which is a substitute for a campfire, burns wood or charcoal, and uses only a little fuel.

In addition to battery lighting, I have numerous kersone lamps, and therefore useing the same fuel for cooking is desirable.
