Tinny makes alcohol stoves for just about all types of cooking, from esbit replacement to slow simmer stoves. For freezer bag cooking, I use the ssbit stove, hardware cloth pot stand, heiny can pot, and an aluminum wind screen (from a flimsy grocery store cookie sheet). Total weight ~3 oz. As far as cooking food in a pot, I use a nion #2, hardware cloth pot stand, walmart grease pot, and a similar aluminum wind screen. This kit is ~6 oz and with the addition of a very small (albeit heavy) spring form pan that nestles in the grease pot, I can even bake biscuits, pizza, cinnamon rolls, and the like.
