Pork Shoulder – look for what butchers call a “Boston Butt”, despite its name it comes from the shoulder, 6 – 10lb is good for A LOT of sandwiches
Wood for smoke – I prefer hickory for pulled pork but oak, apple, or maple would add interesting flavors as well
Patience - or beer, that works too
Buns – good buns, again…everybody likes good buns.
