I did some ribs from Costco yesterday and they turned out great. A package with two racks cost around $20. There was a lot of meat to trim from them, and the trimmings (after cooking along with the ribs for about three hours) went into some baked beans. [p]I made my own rub with turbanido sugar, salt, chili powder, paprkika, cayenne pepper, onion and garlic powder and oregano. I gave both racks a light coating, without mustard.[p]I cooked them indirect (drip pan on the grid, second grid on the drip pan, ribs on the second grid - no platesetter or other barrier needed) at 250 for about 6 hours. I didn't use any foil and I didn't flip the ribs or add any sauce. I just left them where they were and sprayed them with apple cider a few times.[p]When the ribs looked ready, I took them off and put them in a foil pan while I grilled my corn.[p]Everything came out great. Me and my guests finished most of the first rack, and I gave them half of the second one to take home. I'll be having the leftovers for dinner tonight.[p]Next time I'm going to try them direct on a raised grid.
