I usually get my butts around 4-5lbs and they take a good amount of time to cook. If I cut them in half down to about 2-2.5lbs in theory they will cook in half the time. So my question is, will they cook to fast and not have adequate time to break down all the tissue? Also when cutting a butt in half dose one half still have the bone or would I cut out the bone then cut it in half?
