Grilled Prime Rib
(from ksox’s recipe box)
The ideal air temperature in your grill is between 300-325 degrees. A charcoal fire made with half charcoal and half hickory chunks (chunks about the same size as the charcoal) is the ultimate heat source. For gas grills, soak plenty of wood chips, burning them in a metal grilling box in the hottest part of your fire to add a nice smoky flavor!
If your roast is wrapped in fat, remove and season under the fat with your favorite blend, replacing fat if desired. A roast tied in fat is self-basting. A roast with no fat wrapped around it will brown more and have a smokier flavor.
Roast using the chart below as a guideline — test with a reliable meat thermometer when your estimated time approaches. Remove at recommended temperature, cover and rest 10 minutes before slicing (the temperature will rise about 10 degrees. Charts are meant as guides only, conditions vary. There is no substitute for your good judgment and a dependable meat thermometer!*

Serves 12 people
- 10 lb. rib roast
- 1/4 cup freshly ground black pepper
- 2 Tbsp. ground cinnamon
- 2 Tbsp. Kosher salt
- 1 1/2 tsp. ground thyme, crushed
- 1 1/2 tsp. garlic powder
- 1 tsp. onion powder
Mix together all the ingredients in a small bowl. Rub on all sides of the prime rib to coat, and then roast or grill the prime rib. You can also place the prime rib in the refrigerator overnight (wrapped in plastic wrap), to enhance the flavors of the rub.
Allow the roast to stand at room temperature for 30 to 40 minutes before grilling.
Grill the roast, bone side down, over indirect medium heat (350°F to 450°F). with the lid closed, until cooked to desired doneness, about 14 minutes/pound for medium rare. Transfer the roast to a cutting board and remove the bones. Loosely cover the roast with aluminum foil and let rest for 20 to 30 minutes. The internal temperature will rise 5°F to 10°F during this time.
