We're doing a beef roast in it this weekend. Cabela's had a cast iron shelf/table for use with Dutch ovens so that you don't have to put it in the fire pit.
DH fashioned one for us using a grate type table his father made for making shore lunches and a cast iron griddle we never use. It should work well. Same principle as the Cabela's table, but free.
I'll let you know how it works. I'm looking forward to it, but am nervous.
Cast iron cooking is an art unto itself. My Nana was an "artist" and it was all she used, on a wood burning stove no less.
