Slow Cooker Pulled Pork

We've been trying to develop the perfect pulled pork recipe with a great savory sauce, not too sweet but very flavorful. Although our attempts with the smoker have been pretty good, this slow cooker recipe is pretty impressive. This recipe is adapted from the kalyns kitchen website recipe for slow cooker pulled pork: http://kalynskitchen.blogspot.com/2009/10/slow-cooker-recipe-for-pulled-pork-with.html

I found kalyn's recipe for Slow Cooker Recipe for Pulled Pork with Low-Sugar Barbecue Sauce intriguing and prepared it with a few simple adaptations:

Slow Cooker Pulled Pork
(Makes about 6 generous servings. Recipe adapted from Slow Cooker Recipe for Pulled Pork with Low-Sugar Barbecue Sauce from Kalyn's Kitchen, which is adapted from the Slow Cooker Pulled Pork recipe from Prudence Pennywise.)

3 lb. boneless pork loin roast (trim all visible fat; roast should be slightly smaller after trimming)
olive oil, for spraying crockpot
1/2 cup tomato sauce
2 tablespoons tomato paste
4-6 tablespoons hoisin sauce (available at Asian grocers and most regular grocery stores)
1/4 cup apple cider vinegar
1/4 cup yellow mustard
2 teaspoons green Tabasco or 1 teaspoon red Tabasco
1 1/2 tablespoon Worcestershire sauce
1/2 teaspoon liquid smoke

Drizzle olive oil in crock pot; use paper towel to rub olive oil over bottom and sides of crock pot. Trim excess fat from pork loin roast, then cut in half against the grain and place both pieces in crock pot.

Combine tomato sauce, tomato paste, hoisin sauce, apple cider vinegar, mustard, Tabasco, Worcestershire sauce, and liquid smoke and whisk together, then pour over roast in crock pot.

Cook at low temperature for 7-8 hours, or until meat shreads apart easily. Shred pork roast with two forks.

If sauce is too thin after pork roast is done, remove pork to cutting board, pour sauce into saucepan and simmer until thickened. Use two forks to shred pork, then recombine shredded pork and sauce.
