Its a butt for cryin' out loud. Supposed to be idiot proof, right? I just threw almost a whole butt out due to being practically inedible. 5 lb piece of meat rubbed with Jeffs rub and smoked at an avg. of 240 for 8 hrs using pecan and oak. Sat for a couple days in the fridge wrapped in foil then reheated in the oven for 2 hrs at 220. It was tough, dry and flavor less. I dont get it. Any thoughts?
