1/4 cup sweet paprika
3 Tbs firmly packed brown sugar
2 Tbs dried oregano
2 Tbs granulated garlic
1 Tbs ancho chili powder
2 tsp kosher salt
2 tsp fresh ground black pepper
1 tsp celery salt

Thoroughly combine all the above ingredients.  Techniques for applying the rib rub prior to taking to the barbecue pit:   Remove the membrane on the inside curved part of the rib.  This allows the seasoning to penetrate that side of the meat also.  Using a pastry brush, apply a thin coat of yellow mustard to all sides of the ribs.  This helps the seasoning to stick to the meat, offers a conduit to deliver the seasoning into the meat while cooking and helps set up a tender, flavorful "crust" on the outside of the ribs.  The mustard flavor dissipates totally leaving no trace of any mustard flavor.
