I see references to cooking two butts/shoulders at a time, but what about only cooking one?  How does that affect cook time?  I usually wind up cooking for one or two and I don't have a dedicated freezer, only that which is at the bottom of the fridge (and it's an average-sized fridge), so I don't want too much for the freezer.
Thanks in advance!
