i've used catering sized cans of beans as cooking pots before now, usually over an open fire, however if i'm hiking i usually use my 10+ year old set of pots from when i did duke of edinbrough. they are made by optimus, weigh about 550g, and are made up of a small pot, a larger pot, whose lid is also a frying pan. they are a bit dented now mind, but on the plus side in the small pot i can keep, my pocket rocket, lots of coffee/hot chocolate, a pan scrubber, the pot grips, matches, wind break, so i've all i need to brew up! bit off the topic i know but i got rambling on;)
