1/2 to 3/4 cup packed brown sugar
1 can (6 ounces) tomato paste
1/3 cup barbecue sauce
1/4 cup whiskey
2 tablespoons liquid smoke
2 tablespoons Worcestershire sauce
3 garlic cloves, minced
1/2 teaspoon chili powder
1/2 teaspoon salt
1/2 teaspoon pepper
1/2 teaspoon hot pepper sauce
1/4 teaspoon ground cumin
1 boneless pork shoulder butt roast (3 to 4 pounds)
1 medium onion, quartered
8 hamburger buns, split
In a small bowl, mix the first 12 ingredients. Place pork roast and onion in a 5-qt. slow cooker. Add sauce mixture. Cook, covered, on low 6-8 hours or until pork is tender.
Remove roast and onion. Cool pork slightly; discard onion. Meanwhile, skim fat from sauce. If desired, transfer sauce to a small saucepan; bring to a boil and cook to thicken slightly.
Shred pork with 2 forks. Return pork and sauce to slow cooker; heat through. Serve on buns.
