I have been able do do some basic cooking with the Pocket Rocket when I want. I think cooking's harder in Ti pots than Al; Al seems to keep the heat a little more even. But either way, I think if you want to cook bring olive oil helps to keep stuff from sticking (it will still stick if you let it) and helps distribute the heat to the food better.

I have a home made alcohol stove, Pocket Rocket, and whisperlight in my regular use stove pile. I do tend to use the whisperlight for cooking trout and other actual cooking, as opposed to the other stoves where they are mostly used for boil and bag style cooking. Never used esbit before, but I know some people like it for light weight boil and bag . Hopefully it works better than Sterno did.
