i picked up what i was told was a 10lb shoulder the other day. i need it for a party today at 1:30 so i figured the time out to have it done around noon so it could sit for a while, including traveling time. i put it on around 8pm last night. it's now 8am and i got something weird happening. it looks like half of it is done and the other half isn't. is this possible. it's basicaly split by the bone. the meat on one side of the bone is real tender and breaking off and on the other side it clearly needs more time. does this even make sense? i've only ever done butts so i have no idea how a whole shoulder cooks. would it make sense to break off the done side and wrap it up and let the rest keep going?
