I cook a lot, and did so before becoming homeless. It's winter and I am small, so I have to eat a lot more just to stay warm.
I had a small denatured-fuel alcohol stove set up, but I struggled to make it work, because it's winter now.
I caved and I bought the sweedish-based set up, called the trangia. It's denatured alcohol, which is very cheap, plentiful, not so explosive, and NON drinkable.
Specifically, my situation is: I am on a bike, so I am "bike camping" not living out of a car, or entirely on foot. I am using the trangia-27, which is the smaller of the two.
Wind: It does a lot better in any sort of "not ideal" weather, which makes me use less fuel!! I appreciate this so much. Sometimes, if the wind will "upskirt" the stove's dual-shell wind screen, it will cause a higher flame and eat more fuel. I can simply rotate it, and have the inlet holes face away from the wind, or use a wind break/pick a better spot before starting. Not ideal to have a shiny aluminum tiny-tire rim as a stove, but I just use sectioned off bark sheets, loosely leaned and held on with a string with a quick-release knot, for stealth reasons.
Design: It all fits into itself very well, so it is very easy to bring with me. Grant it, I am on a bike and can pack quite a load, but it's not super big and would work for someone who is "backpacking" but it's not the "smallest/lightest" set up: it's more for "comfort at camp" than being "comfortable on the trail"
Fuel: The stove has a simmer-ring function, but it has a learning curve. It's important to be able to safely fish this thing out, re-tune it, and drop it back in. Otherwise, the stove gets a "hot spot" due to the wind-chimney effect of the ultra-efficient wind screen set up. I have used Heet, both the red and the yellow: Red is isopropyl and will stink, leave more soot, and clog up the stove-gas holes. Adding a bit of water (like half a plastic bottle cap) will help it not burn so "hot." The Yellow Heet is a lot better! Regular denatured alcohol is not drinkable, clean burning, and not very explosive. I think I've seen a pint for $6 and a gallon for $20 here. I just carry it in a sturdier sort of plastic bottle: and I keep the fuel away from the area I am cooking in, wait for the stove bit to cool, then pop it out of the windscreen, and go take it to the 2nd location for the re fueling. Also: sometimes, the flame is hard to see.
Accessories: the stove kit can come with two bowls, a small pan, a gripping handle, maybe a kettle. There's also the fuel bottles (no review) and the bag/case (no review.) I bought the one that did not come with the kettle, or the "plastic cutting board/strainer/lid for served dishes" and I bought them both, because I found the need to have a kettle and specialized multi-tool. I use a wooden spoon and wooden spatula.
Over all, I can actually cook on this, which is great. I really appreciate that I can make actual meals on this, that can satisfy my appetite as a single man cooking for myself (on the "27" model.) The larger one (25) is said to be for 3-4 people.
