Awesome Pulled Pork BBQ

Step 1
Place pork in a slow cooker and season to taste with garlic powder, poultry seasoning, salt, and pepper. Add quartered onion, apple, and 3 celery stalks. Pour chicken broth into slow cooker.

Step 2
Cook on Low until very tender, about 8 hours. Transfer pork to a large platter and discard juice and vegetables. Shred pork with a fork and return to the slow cooker.

Step 3
Prepare barbecue sauce while pork is cooking. Melt butter in a large saucepan or small Dutch oven over medium heat; cook and stir 2 cups celery and 1 1/2 cups onion until onion is translucent, about 5 minutes. Add ketchup, water, vinegar, brown sugar, Worcestershire sauce, mustard, liquid smoke, and 1 tablespoon garlic powder; mix. Reduce heat to low and simmer, stirring occasionally, until sauce is thickened, about 10 minutes. Pour barbecue sauce over shredded pork.

Step 4
Continue cooking pork on Low heat until flavors combine, about 2 hours.
