BBQ Pork Two Ways (crockpot and stove top)

I got this recipe from All Recipes and it has been a family favorite for years.  I do this in the crockpot to make it easy.

BBQ Pork Two Ways

2 1/2 lbs. pork shoulder
1/2 cup chopped onion
1 clove garlic, minced
1/4 cup brown sugar
1 tsp. dry mustard
1/2 tsp. salt
1/4 tsp. ground black pepper
2 cups ketchup
1/4 cup Worcestershire sauce

1.  Cut boneless pork shoulder crosswise into 1/4" slices.  Partially freezing it will make slicing easier (I often just cut it into large slices)

2.  In the slow cooker, combine sliced pork, onion, garlic, brown sugar, dry mustard, salt, pepper, ketchup and Worcestershire sauce; mix well and cover.  Cook on low for 6-8 hours or until the meat is tender.

3.  OR In a Dutch oven or large saucepan, combine ingredients, and cook over medium high heat and bring to a boil.  Reduce heat and cover.  Simmer, stirring occasionally for 2 1/2-3 hours or until pork is tender.
