I use a Heineken-can penny stove with denatured alcohol. Some people hate these things. I've found it to be very efficient and versatile with a simmer ring. I can boil water to make pasta, rice or beans for dinner. In the mornings, I use it to make coffee and then add a simmer ring to make pancakes.

I usually have a 50/50 mix of S-L-X denatured alcohol and HEET. If that runs out, I can find either one of them at almost any gas station or hardware store. Heck, if a liquor store is the only place around, ever-clear works almost as well.

In the picture, you can see the stove in the wind-block on the right, my soda-can percolator on the left and my coffee in the middle.
