Heat your pellet smoker to 250. Lay foil across the grill underneath the warming rack of the smoker to block direct heat from hitting the ribs.

Rub the ribs evenly with a light coating of yellow mustard, and an even layer of your rib rub. Once the smoker is up to temp, place the rack of ribs on the warming rack, in the center of your smoker. Smoke at 250 for 4-5 hours, until the meat pulls back from the bones. Starting about 2 hours into the cook, every 30 minutes use a spray bottle filled with apple cider vinegar to lightly spray the ribs.

During the last 30 minutes of cooking, brush with bbq sauce and allow to tack up during the final 30 minutes of cooking. Allow to rest 20 minutes at room temp before cutting and serving.
