how long to cook a 10 pound pork shoulder per lb
A 10-12LB pork shoulder cooked at 225 for about 14 hours is done. You'll use probably 25LBs of charcoal to achieve this, and your hair will smell like smoke for 2-3 days even after washing.:). I only apply smoke to shoulder/butt for the first 4 hours or so...after that it doesn't do much good other than dry it out. 10-12LB pork shoulder cooked at 225 for about 14 hours is done.
