Bought a 7 bone (19+ lbs) PRIME prime rib from Costco for Christmas eve dinner. It was prepared conventionally in my son's oven. I was overruled on smoking. Also King Crab legs also from Costco. Placed on a large jelly roll pan and placed on his gas grill, medium heat for 20 minutes. Both beef and legs absolute perfection.
Sure wish the beef had been smoked but overall, very tender and tasty.
