My SAR pack routinely included a small pan and a Trangia. It was dead simple, allowing one to devote attention to other matters while food or water was cooking. If really cold temperatures were on the dance card, I would usually replace it with a SVEA or a small cartridge stove.

In a stark survival situation, I would go with a campfire. You don't need to carry all that much to insure proper and continued ignition, in most situations. But circumstances do vary, don't they?
