Smoked Prime Rib Roast
Do not use a roasting pan and a V-shaped rack. Doing so will block the airflow around the lower third of the meat resulting in under-cooked meat and a soggy crust. If you want to save the juices for an au jus, place a pan on a lower shelf or place a flat roasting rack on top of the roasting pan.
If your guests prefer a more well-done slice, heat some beef broth in a frying pan to boiling, reduce heat to a simmer, and place the slice of roast in the pan for about 30 seconds; flip and cook for another 30 seconds. But you will lose the gorgeous pink color.
Use 1/2 teaspoon salt per pound of roast for salting.
You can also smoke the meat on a grill using hickory or pecan wood. Turn grill up to highest temperature to do the reverse sear.
