You probably all know that Trangia started making duossal pans again. The idea of duossal is primarily more durability than the other offerings at the expense of a little more weight. I've read they also cook better due to more even heating and maybe slightly better heat retention. I ordered the 3 for my Trangia 27. I look forward to testing them out, and once I get them I'll weigh them for you. Also, the last few days I've been cooking 1/3c brown rice +1/3c brown lentils, pre-soaked overnight in the refrigerator, on the Trangia. I'm noticing it consistently uses approx. 1/2 stove of fuel. I didn't weigh or measure it, so I don't know how much that is though the Trangia holds 70ml/2.37 oz. I bring it to a boil, reduce it to a simmer for about 25 minutes, then shut the stove off and let it sit for another 20 minutes. I've read online that the Trangia uses 32ml of fuel to boil a liter of water. I used a 1 liter pan, with rice, lentils, peppers, onion, broccoli and spinach. This is probably very close to my fuel usage. Compared to a gas canister with the little Fire Maple stove, I don't have exact times, but it seems to take a little longer on the Trangia. No surprise there.
