Mix up the Rib Mop Spray in a food safe spray bottle
Season both sides of the ribs with the rub. Approximately 1.5 tablespoons per large meaty rack of ribs. Less if your ribs are on the thinner side.
Add one chunk of fruit wood to the smoker and place ribs on smoker meat side up for 5 hrs, dependent on thickness of ribs.
Check for the ribs every 30 minutes at the 4.5 hour mark to see if they are done, continuing to spray the ribs with the Rib Mop Spray. You know your ribs area ready to take off when.... you pick up the ribs with tongs, the ribs should bend easily at the halfway point and the bark should start to crack slightly as the ribs bend.
Flip over the ribs meat side down to cut between the bones more easily.
