I usally do 2 or 3 racks of baby back ribs and love them using the 2-2-1 method. My question is; if I'm cooking for a large group and want to do say 10-15 racks how can I go about that. Do you guys still wrap each rack or just smoke them straight until there done. if in a rib rack can you wrap the whole rack up? last question, if you just smoke straight through without wrapping in foil, how long?
