1.5 tbsp sweet paprika (3tbsp) (Edited Feb '12 to say I've also used mild smoked paprika with fantastic results)
1 tbsp light brown sugar, lightly packed (2 tbsp)
1/8 tsp cayenne pepper (1/4 tsp)
S&P to taste (about 1 tsp each is what I used)
2 lbs pork (baby) back ribs (6 lbs) - leave the membrane on the ribs to help hold them together
1 cup barbecue sauce (3 cups)
Vegetable oil spray.
