We have a trangia. Cooks in any weather. (So they say, but we are not proposing to test it out - fair weather campers here. ) But have cooked outside in the drizzle before. You can cook on the ground but I got a little folding shelf type thing from Wilkinson to sit it on. We have a little roll slat table too for stuff.
As for keeping stove away from DC, that's more than I know. If you locate it at the end of the universe they will still make a beeline for it. It's a great mystery to me. If anyone knows the solution please post.
We have a Trangia from before the kids came along but I don't think I would rely on it for dinner for 4. It is probably do-able if you have a BBQ or don't mind part of the meal going lukewarm while you cook the rest. We only have the meths burner version for now, but if you're going to go for it, I'd get a gas burner as it'll cook everything 10x faster
We have a single ring stove which we keep on a table at the edge of our extension. TBH we only use it for the first tea/coffee of the day and emergencies if we are having a campfire disaster eg. damp wood and hungry kids. Having said that we have just bought a kitchen unit thingy with cupboards underneath and will try it out this weekend.
We feed a family of 4 with our trangia. We do things like rice or couscous - trangia cooks rice like a dream - wrap up cooked rice/couscous in tea towel, fry up some chorizo/egg type things or open tinned fish, chop up some veg. Mix and eat. Or fry hotdogs. Or heat up soup. To eat with bread. Or variations thereof.
I brought one of those £10 halford stoves. It was speedy quick when I tested it out with making coffee and toast in the garden yesterday. So we won't starve! Will try out pancakes, and some sort of lunch at the weekend.
I need the stove to be visible. Otherwise DS will do a forward roll into a pike shape into it.
