1. If you like, cut the pork butt into medium (2 to 3-inch) chunks (the ribs don’t need to be cut up). 2. Put the whole butt or the pieces in a large bowl or directly into a large slow cooker (at least 5 quarts). Sprinkle the meat with the rub, turning the butt to coat evenly. Add the bottled smoke. 3. Cover and cook on high 5 to 6 hours or on low for 10 to 12 hours until the meat is pull-apart tender and reaches an internal temperature of 190° F. 4. Using tongs and a slotted spoon, transfer the meat to a rimmed platter or baking sheet. Let rest until cool enough to handle. 5. Pull the meat into strands. It should shred very easily. Serve the barbecue piled on buns with your favorite barbecue sauce. 6. To serve the barbecue later, cover and refrigerate the meat when it has cooled. Pour the meat juice into a separate container and refrigerate. Before reheating the juice, skim and discard the congealed fat layer on the top.
Big Oven Butt A big pork butt cooks to pull-apart tenderness as well in an oven as in a slow cooker. It’s up to you so choose your weapon. Heat the oven to 300° F. Place the pork butt in a large roasting pan. Coat the outsides generously with the dry rub. Pour in the bottled smoke. Cover the pan with heavy duty aluminum foil. Roast 5 to 8 hours, until the meat is pull-apart tender and reaches an internal temperature of 190° F.
