This prime rib recipe involves covering the roast in Dijon mustard, seasoning with a rub or simple salt and herbs, then smoking it at 325 degrees with pecan wood for approximately 4 hours. The perfect medium rare is achieved when the internal temperature reaches 128-130 degrees, followed by resting the meat for 20-30 minutes before slicing. Serve with horseradish sauce and roasted garlic for a delicious meal.
