Step 1

Place ribs in slow cooker. In a medium bowl, combine BBQ sauce, onion, celery, mustard, brown sugar, Worcestershire, and garlic. Pour over pork.

Step 2

Cover and cook on low 10 to 11 hours or high for 5-1/2 hours.

Step 3

Remove ribs from cooker. In a small bowl, combine cornstarch and cold water.

Step 4

Strain BBQ sauce into a saucepan set to high. Stir in cornstarch mixture. Then bring to a boil and stir constantly until BBQ sauce thickens. Remove from heat.

Step 5

Place pork back into slow cooker and pour BBQ sauce on top. Turn pork so that it is covered with sauce on all sides.

Step 6

Remove pork from slow cooker and serve with sauce (set aside about 1 cup sauce to use later for pork sandwiches!)

Step 7

To store, mix pork with just enough BBQ sauce to coat it and save the remaining sauce in a separate container. Refrigerate both until ready to use.
