Remove silver skin from the back of the ribs by inserting a butter knife under the skin. Grab a paper towel and grab the membrane and pull off the back of the rib.
Rub yellow mustard on both sides of the ribs.
Pat ⅓ of the dry rub onto the underside. Flip over, add the remaining rub to the meaty side of the ribs.
Place on the smoker for 2 hours. (Do not open the smoker for at least 2 hours).
Remove from the smoker and place on aluminum foil large enough to contain the juices around the ribs.
Add remaining ingredients.
Seal the foil around the ribs and place back on the smoker for another 2 hours.
Open the foil to expose the ribs and smoke for an additional one hour.
Remove from the smoker and let the ribs rest for 20 minutes in the foil before serving.
