In a medium bowl, whisk together the barbecue sauce ingredients. Pour over the pork and use your hands to make sure the pork is well-coated.
Cover and cook on LOW for 8 hours.
Carefully remove the lid (hot steam will escape). Increase the heat to HIGH. Use two forks to shred the meat and mix it well with the sauce (remove the butcher twine if needed).
Cover and cook until slightly thickened, 15-30 more minutes, then serve.

Notes
Normally I'm not a fan of buying specialty ingredients. But in this recipe, I find that smoked salt (available on Amazon) really does enhance the flavor of the BBQ sauce and of the entire dish. So it's highly recommended.
