Patrick, are you certain they are boneless "back" ribs, and not boneless country-style ribs? Personally, I've never heard of, or seen, boneless back ribs. Not that they don't exist, I've just never seen them. I'm really not sure how they would make them boneless, or what the point would be! I mean, the bone is a handle, and pulling the meat off it is half the fun!! ;D
