Bring your offset smoker to temperature – You will want to maintain a temperature of roughly 250 degrees throughout the entire smoking process.
Prepare the rib roast – Bring the rib roast to room temperature. Trim any excess fat off the rib roast, especially the fatcap, which is the thickest and most dense part of the fat on the top of the roast.
Rub the rib roast – Completely cover the rib roast with the ribrub, gently patting it in place. Be sure to cover any nooks and crannies aswell. You can’t use too much rib rub!
Place the rib roast on the smoker – Place the rib roast on the 8” x 10” wire oven rack and place it into your smoker. Smoke until the internal temperature reaches 120 for rare or 130 for medium. For a 7 pound rib roast, at a smoking time of 35 minutes per pound, this will take you roughly 4 hours.
Remove the rib roast from the smoker – Let the rib roast stand for 30 minutes before carving. Slice the roast right in half between the two bones. You now have two very large steaks with the bone attached. Each one of these steaks will serve 3 people.
