This makes a great gravy! If you cannot grill it, roast it instead, for about 2 1/2 to 3 hours at 325 degrees-uncovered-basting every 30 minutes. Estimates for grilling are 15 to 18 minutes per pound but this will be on the high side because it is CHILLED for awhile thus making the pan, etc. cold which will affect the grilling times. We have a WEBER grill and DH does not want to remove the hot grate too often, so that is why the technique is as stated here.
