I used to make the greatest meals, breads, bannock, and fruit breads in a Dutch oven when I was a kid as a scout.  I gave that up of course portaging the BWCA and Q as an adult.  I had a brain storm (ouch!) recently that a person could talk a thick gage aluminum foil with and construct a type of Dutch oven, lay it in the coals, and bake some tasty concoctions.  Has anyone tried this before?
