Season ribs the way you want. Smoke them for 3 hours at 225 than spray them with apple cider vinegar wrap with aluminum foil and continue to cook at 225 for 2 hours then unwrap apply your favorite BBQ sauce or just spray with apple cider vinegar again and cook at 225 for one more hour. Remove from smoker. Pull the bones out. They slide out easily slice up an onion. Cut boneless ribs into sub bun length add ribs onion cheese and more BBQ sauce to a sub bun and you will never have a mcrib sandwich again.
