Made my first attempt at smoking a prime rib for Mother's Day and have to say I may never order from a restaurant again. Turned out amazing. Used the Jimmy J's Au Jus recipe to finish it off.
Applied a light rub the night before and then pulled and let get to room temp at 630am.
Put on the smoker at 10am and randomly checked IT about every 1.5hrs.
Smoked for roughly 5 hrs @ about 210 using mesquite and cherry wood.
Pulled when IT hit 135* and then let it rest in the cooler for about an hour.
