Barbecue Cookout Pulled Pork

My brother created this recipe a few years ago. It's great for family gatherings, games days, or make-ahead meals. Many of the ingredients (garlic, chili powder, worcestershire) are easily adjustible, so feel free to modify to your particular taste. NOTE: This recipe does not resemble - nor was it intended to resemble - the style of pulled pork made in North Carolina.

• Ready In: 8 hrs 15 mins
• Serves: 6-8

Ingredients

• 1 (3 lb)  pork roast, trimmed of all fat
• 2  cups onions, chopped
• 1⁄2 cup brown sugar, packed
• 1⁄4 cup white vinegar
• 6  ounces tomato paste (small can)
• 1 1⁄2 tablespoons chili powder (the hot stuff. Chipotle works well, too)
• 1  teaspoon dry mustard
• 2  teaspoons Worcestershire sauce
• 1⁄4 cup water
• 2  teaspoons salt
• 3  garlic cloves (add or subtract to your heart's content)
•  pepper

• For Garnish

• 8 -12  kaiser rolls
•  horseradish

Directions

1. Add all ingredients EXCEPT PORK to the slow cooker.
2. Divide pork into quarters.
3. In a heavy-bottomed pan over medium-high heat, sear pork on all sides.
4. Add the pork to the slow cooker and mix with the sauce.
5. Cook for 8 hours on low.
6. After cooking time has completed, use two forks to pull the pork apart. If you are unable to shred the pork, it isn't fully cooked yet.

9. EAT!
