Chop the pork butt into healthy cubes for maximum bark surface area.
Smoke the pork at 325°F for about 5 hours until it reaches an internal temperature of 170°F.
Wrap the pork in a foil pan with apple juice, barbecue sauce, and additional rub. Seal tightly and continue cooking until the internal temperature reaches 205-210°F.
Once done, let the pork rest for a while before shredding.
Shred the pork in the juices and mix in remaining rub for added flavor.
