This has been my go to pork butt rub recipe for 20 years. It's six simple ingredients that causes everyone that has had my pulled pork to mark their calendar for when their next opportunity is to come over and eat it again.
Amount for an 8 lb butt:
1/4 cup black pepper
1/4 cup paprika
1/4 cup turbinado sugar
2 Tbsp coarse salt
2 tsp dry mustard
1 tsp cayenne pepper
