Slow Cooker Pulled Pork

This is by far the best pulled pork I have ever had! Thanks Bridget Mc!

Slow Cooker Pulled Pork (spice rub from Cooks Illustrated and The Way The Cookie Crumbles)

Spice Rub:
1 tablespoon ground black pepper
1-2 teaspoons cayenne pepper
2 tablespoons chili powder
2 tablespoons ground cumin
2 tablespoons dark brown sugar
1 tablespoon dried oregano
4 tablespoons paprika
2 tablespoons table salt
1 tablespoon granulated sugar

1 (6-8 pound) bone-in pork shoulder (I used a pork end roast)
2 cups barbecue sauce
1. Mix all spice rub ingredients in small bowl.
2. Massage spice rub into meat. Wrap tightly in double layer of plastic wrap; refrigerate for at least 3 hours. (For stronger flavor, the roast can be refrigerated for up to 3 days.)
3. Unwrap roast and place it in slow cooker liner. Add liquid smoke, if using, and ¼ cup water. Turn slow cooker to low and cook for 8-10 hours, until meat is fork-tender.
4. Transfer roast to cutting board; discard liquid in liner. “Pull” by tearing meat into thin shreds with two forks or your fingers. Discard fat.
5. Place shredded meat back in slow cooker liner; toss with 1 cup barbecue sauce, and heat on low for 30-60 minutes, until hot. Serve with additional barbecue sauce.
