Gill,
Here's my morning coffee gotta go to class soon daily advice:
If you're doing bushcraft, yeah, you'll do fine with what's been posted here already.
If you're climbing, doing an extended trip, or you'll be at altitude, take a real stove, either a Trangia (burning meths produce carbon di-oxide, co2, water wapour, so you won't die of fume inhalation) or a petrol stove, (burned petrol produces carbon di-oxide, that stuff that used to kill miners).
If you want to cook INSIDE a tent, a Trangia will do nicely.
If you don't want to use meths for whatever reason, most modern expedition tents come with a large vestibule that allows you to cook, smoke, lace up your boots and not got completely soaked. Plus, if you're too lazy to get out of your bag, you can lie in your tent and reach out the door and cook under the vestibule. Yeah that's right, I've done it!
Cheers mate,
Adam
