Then there is the choice of stove, as some else has already mentioned. If you use a Pocket Rocket, be prepared for burn marks right in the middle of the pot. It has a seriously focused flame – to what end I do not know. I never did trust that stove.
But if you use a stove with a wide head that throws the flame sideways so the heat is spread out over the whole base of the pot, then you can COOK. There are plenty of uprights and inverted canister stoves with wide heads or wide flame spreads.
As illustrated earlier, I can cook real food in a Ti pot quite easily, and so can many others.
Cheers
