Sorry, they are baby backs. Yes I've read so much on this site, BGE's site, Naked Whiz, etc, that it's all running together now. I read Mike's version where he uses the plate setter but just wondered if I NEEDED one or something like a drip pan, for my first ribs, or if I can cook without anything today unitl I get one. The video on BGE's site doesn't look like or mention using anything when he cooks ribs yet he specifically points out that he's using one in other videos. Will the drippings cause a huge mess in the bottom? They will be cooked flat on the rack, not vertical.
