After 3 hours of cooking, check to see if any racks are ready to come off the grill. They are done when the meat has shrunk back from most of the bones by 1/4 inch or more. When you lift a rack by picking it up from one end with tongs, the rack should bend in the middle and the meat should tear easily. If the meat does not tear easily, continue to cook the ribs. The total cooking time could be anywhere from 3 to 4 1/2 hours.
05Remove and tent loosely with foil. Allow ribs to rest for 10 minutes.
06Ribs can also be cooked in smoker at 225 degrees for about 4-6 hours.
