Pulled the prime rib from the smoker at 123*, let it rest under loose foil for 40 minutes, and reversed seared it in a 550* oven for about 5-6 minutes. It turned out a good medium rare...I used au jus to darken the meat for those that liked well done. Very tasty and moist. Twice baked potatoes, salad, green bean casserole, rolls, wine...all good. Oh, and cheesecake, homemade.
