If any of the varieties of alcohol are available as a fuel source, I would (and do) carry a backup alcohol stove. There is a vast literature on alcohol stoves; many are light, cheap, easily improvised from aluminum food cans, and effective.

The heaviest and most expensive backpacking type is the legendary Trangia,, weighing all of 3 oz. and costing about 12 bucks - hardly a deal breaker. I believe HJ is going to discuss the might T in a future SOTW.
