Remove membrane from ribs and season on all sides with Pitmasters Pick BBQ Rub.
Place ribs in the smoker for 2.5 hours. After the first hour, spritz your ribs with water to help keep them moist. Continue spritzing every 30 minutes or so or when you notice the ribs are drying out.
After about 2.5 hours, the bark should be set, and your ribs should temp around 175°F.
Wrap ribs meat side down in foil with brown sugar, pats of butter, and honey.
Place the wrapped ribs back in the smoker for another 1.5 hours.
Unwrap the ribs from the foil, flip them meat side up and glaze with Korean bbq sauce. Continue to cook them for another 30 minutes.
Garnish with toasted sesame seeds and sliced green onions.
