I will burn my battery inflated mattress before I try to boil some coffee water over an Esbit fire
Fishmonger, you need to get out more often.

Yeah, if you use the "out of the box" ESBIT stoves, they're pretty awful, but there are good set ups out there. The Bobcat system from Flat Cat Gear works very well. If you use the Epicurean stove in the low mode, there is no smell.

Makes dandy muffins too.
