Esbit Solid Fuel Tablets

Work well. Not odorless, though!

I almost feel a bit silly leaving a review for these — they're so straightforward.  Esbit tabs are compact, fairly easy to light with a match or lighter, and quickly put out a good amount of heat. I use mine in the Esbit collapsable (Pocket) stove and can rehydrate a meal with one tablet in a reasonable amount of time.

The packaging might say odorless, but I don't think that's true. Maybe I just have a sensitive nose, but I need to keep these in a double ziploc bag once opened to keep their fishy smell in.

A few of these and the pocket stove are more than enough for a weekend excursion, especially if you're only cooking for one. Don't expect this to be as quick as your butane burner, but it works fine.
