For sugar and chocolatey goodness, try to see if you can find something called "Choclettoes". They are a walnetto without the nuts; think of it as chocolate bullion. <img src="/images/graemlins/smile.gif" alt="" /> They are about the size of a starburst, a little thicker.

Supposedely, if you let one melt in 8oz of hot water, you get hot chocolate. I've only ever found walnettoes here, and the idea of cocoa with nuts sitting in the bottom of the mug is too odd for me, so I've never actually tried this recipie. It's from my grandmother. They might be more space efficent than cocoa pouches, becuase you aren't packing air, but they only have about a six month storage life, and you'll want to put them in a tiny ziplock becuase the might melt at very high heat. Putting a mouse trap in the kit as an anti-pilfer device might be an idea to. <img src="/images/graemlins/smile.gif" alt="" />

As for your pouch, is it a back pack, a shoulder pack, or a belt pouch? And how big?
