You need to upgrade your stove, Esbit's are toys...get a little Coleman and a bottle of fuel at minimum
Some truth to this but-----what's wrong with a toy when I'm only playing about anyway? LOL. It's not like it's there to cook a serious four course meal. Just gonna brew a quick one or reheat rations.
That said, I am always looking for upgrades. What would you recommend for a light, compact single burner?
