If you can't cook over a fire and you have a small group check this out. You can do this over a small stove. I made one of these in about 1/2 an hour 2 weeks ago before I left on a backpacking trip. I had a pot big enough to cook 2 blueberry muffins in and they were great. I put the muffin mix in a couple of those aluminum muffin cups.  It is very easy to use and make. Just be sure to follow the times she has set out for cooking and don't peak. I know its hard to do. Scroll down and you will see how to make one and farther up she talks about cooking in it.   (You need to Login or Register

Sounds a bit like   (You need to Login or Register but requiring an additional appliance.  My paddling partner used the roasting bag approach on last year's trip, while I field tested the reflector oven.  The bag approach is a tad messer; the oven approach a bit heavier.

Yet the approach does have appeal in that you can use a more managable freezer bag in place of the mylar-looking roasting bag.  In addition, you could probably skip using the spiral piece in the bottom of the pan and use small stones instead.  Given a large enough pot, you could also use a diffuser plate inside the pot and not have to carry anything extra at all (except of course for the freezer bag).
