In my BOB I carry a trioxine burner and a few bars, but the bars are hard to find around here unless you order them on-line and a bit expensive for regular use. They do work well in that they will boil about 2 cups or so of water in about 10 minutes or a little over. I use my kit to make lunch at work a lot of the time so I need something that will heat fairly quick but I don't want to spend much on it and it needs to be compact and light weight. So what are some of the methods the rest of you use for cooking or heating food on the go? Has anyone used the pop can stoves much? How long dose it take them to boil a small amount of water?
