I'm looking for a roasting rack that I've seen in the past but can't seem to find. The bottom is the size of a large baking sheet, say at least 16 x 19, looks like a bar cookie pan and has a raised roasting rack above it that looks like a cookie pan cooling rack that covers the entire sheet. I think it would be just the ticket for finishing ribs but I can't seem to locate one. Can anybody point me out to a potential source? Many thanks.
