Combine paprika, salt, sugar, brown sugar, cumin, chili powder, pepper, cayenne, onion powder, garlic powder, celery salt and oregano in bowl; mix well. For a smoother rub, puree ingredients in a spice grinder until well combined and all pieces are uniform (the rub will be very fine and tan in color). This step is important if adding to any homemade barbecue sauce.

Note: Extra rub can be stored in an airtight container for up to six months.
