Preheat your smoker to 225°F (use hickory or a fruit wood).
Remove pork from packaging and wipe dry with paper towels, removing any bone pieces/liquid on the exterior.
7 to 9 lb Pork Shoulder / Boston Butt
Liberally coat the pork on all sides with pork rub. Pat it on—don’t rub it in.
1/4 cup Pork Rub
Place pork in the center of the smoker with fat cap up.
Close lid and prepare the mop sauce:
Add all mop sauce ingredients to a pot, bring to a boil.
3/4 cup Southern Bourbon or whiskey, 3/4 cup apple juice, 1/2 cup ketchup, 1/2 cup cider vinegar, 1/2 cup dark brown sugar, 1 Tbsp lemon juice, 2 tsp Worcestershire sauce, 1 tsp garlic powder, 2 Tbsp stone ground mustard, 1/2 tsp salt, 1/2 tsp pepper
Reduce heat and simmer 20 minutes, stirring frequently.
Every hour, mop the pork with the sauce (use a mop or brush—be gentle so you don’t wipe off seasoning).
When internal temp reaches 170°F (can take up to ~7 hours), remove pork and place in an aluminum pan.
Pour remaining mop sauce over the pork and cover the pan tightly with foil.
Return to smoker until internal temp reaches 201–205°F.
Remove and rest covered for at least 30 minutes before shredding.
Shred pork, discarding large chunks of fat/gristle. Separate fat from the pan juices and pour the juice over the shredded pork.
Serve and enjoy!
