As some of you may know, I found an old cast iron casserole dish yesterday, and now I'd like some recipes to get me started. Perhaps how to convert regular recipes so that they make the best of the cast iron, too. One question I do have is how safe is it have that heavy thing, loaded with food, sitting on an oven rack. Oven racks just seem kind of flimsy to me. Surely cast iron is not exclusively used outdoors or on range tops .... ?
