“I high-lighted the propane gas and the pressure cooker. I think you should get more propane gas. And, the pressure cooker will let you use less gas to accomplish the same work.”
Agree on the propane gas. I still remember exhausting half a bottle (or close to half a bottle) just boiling a few quarts of water for noodles. That was decades ago, and I still remember it like yesterday. I would say figure on one bottle per day if you do any boiling. After that experience, I added gasoline stoves to my mix (I have both). Gasoline goes much further, and is much cheaper, than propane - and will likely be easier to find.
But having said that, unless really well ventilated, I would not mess around with gasoline indoors. Propane is good, but treat it with respect. Assuming small tanks without built-in shut-offs, NEVER leave them connected to anything, as stoves will not necessarily shut off the bottle (and the seal may not be good). But I’ve also had bottles leak, so it doesn’t hurt to put the top of them next to your ear if you need to store the propane indoors. If you can keep it outdoors (and secured) than always store outdoors.
Build a rocket stove cheap and stop worrying so much about fuel; they burn anything:
I have 15-20 of the 20 pound propane tanks. I also have the capability of refilling the small one pound tanks from them. I have both types of Coleman camper stoves, gasoline and propane.
We have a two burner coleman stove and a on burner coleman back pack stove from our days camping when we were young, but I have never liked using propane or storing it.
So I use sterno primarily for coffee or soup. If I was going to cook noodles, in an emergency, I would heat the water to boiling, add the noodles, simmer a bit. Cover and Remove from heat and wrap a towel around or blanket around it and stick it in the non-working oven to kinda finish up. Then reheat as needed before eating. Or you could put them in a thermos to finish cooking.
For beans, soak them before hand, which will reduce the cooking time too. I also don’t like using a pressure cooker, though I have had a few before the advent of the Micro Wave. I may get one to store on the shelf just in case.
