Well, gave it a try. I took two chokes and placed each one in a foil boat. The foil was about 1/3 to 1/2 up the side. I folded the extra foil back down to make a stable base. I put water in each one up to the top of the foil, and a little salt and peper. Cooked 2.5 hours. One hour at 250 and the rest of the time at 300. They looked good, but the leaves were touch and the heart was just tender. Took some photos, but not sure how to post them.
Not a success, but will try again!
