Hmm, a billy pot is a good idea. It's somewhere between a mug and a pot, and quite at home over a small-stick fire. And, the extra capacity is always worthwhile. Time to check the catalogues.

I've seen hard-anodized aluminum ones that are the right size (I think). But I would want one made of stainless steel, with some option for a solid handle. The rim of a stainless steel item cools very quickly and lets you drink tea/soup out of it directly. Believe me, aluminum does not -- a guaranteed scorcher until the contents are lukewarm.
