Ok I cooked a butt for 8 hours at 235 degrees. I wrapped it in foil when meat hit 165 degrees. Then when the meat hit 200 degrees I took it out. The meat was fantastic but what I really want is the meat to fall apart to make pork sandwiches. What does the internal temp need to be at to fall apart? I keep reading 205 but does 5 degrees really make a difference?
