Any advice: I smoked tri-tip on my Pit Boss chip smoker. Process: smoked for 6 hours starting at 110 F, then kept in smoker for 6 more hours gradually increasing temp. Meat tasted smoky. Internal was quite 'soft/juicy'. But the meat was not tender. As in, would not cut with a fork. Seems after that amount of smoking meat would be tender, or? Any advice welcome!
