I started carrying a small alcohol stove with enough fuel for a couple of boils. Hot tea or cocoa and powdered soups can really perk up an emergency menu or even just lunch on a cold day. A few ounces for stove, fuel and a cup-sized pot will work fine.

I've heard that about dog food, but never was willing to try it. Of course if you have a dog along, there goes the dog food!
