I'm going to play with esbit in the next few days with an old pot to see if I mind the gum up. I'm going to try the tabs suggested in this thread. The only thing is it'll only save me 6 grams and I'm so efficient with alcohol stoves...I have them pretty dialed in. Esbit will be fun to play with. Also my hiking partner and I share a stove so time is wee bit of an issue... anything under 10 minutes for both of our meals are good for us
