Hi everyone, I am cooking ribs for the first time this weekend. I figured I would keep the dome temp at 250-275 and cook 4.5 - 5 hours. I was going to use a dry rub on them and coat them with BBQ sauce every 30 minutes or so. Does my time estimate seem accurate and any tips on cooking them? Should I baste with BBQ or spray with apple cider vinegar? What would you suggest?
