I did 4 boneless pork butts (8-10 lbs. each) on Friday to make pulled pork for a small gig on Saturday. Got them on by 8 AM. Ran the cooker at a steady 275-300 the entire cook. By 5 PM, temp on all of them was 200-205. Got them off, let them sit for maybe 15 minutes, and started shredding. First two were beautiful. Easily fell apart. Got to the third one, and I could tell right from the start something wasn't right. Some of the muscle on the outside pulled right off and shredded easily. Then I got to the center muscle and I literally had to "rip" it apart by hand. It wouldn't shred at all. It was horrible! It tasted okay, a little dry, but good flavor. It was really white also. Just odd looking compared to the others. Then the fourth butt, same as the first two. Fell apart effortlessly. Has anyone ever had this happen? Could it have been the butt? Did I do something wrong? Any advice would be appreciated so I can avoid this if possible... Thanks in advance... :blah::blah::blah:
