Rib Rub for Fall-Off-The-Bone Ribs

1. Combine white sugar, brown sugar, seasoned salt, paprika, black pepper, garlic powder, onion powder, and cayenne pepper in a container with a lid; shake until evenly combined.

2. Generously rub both sides of each rib rack with spice rub.

3. Preheat an outdoor grill for medium heat and lightly oil the grate.

4. Place 1 rib rack, meaty-side down, in center of main grill rack; cook 5 minutes, then move to far side of top grill rack, meaty-side up. Repeat process with remaining rib racks.

5. Place rib racks on top grill shelf with meaty sides facing out, stacked one in front of the other at an angle. Turn off heat directly below the ribs; turn other burner on low. Close the grill lid; cook 30 minutes.

6. Flip ribs so the closest side to the flame is the furthest side and the meaty side is still facing forward and the rack that was in the front is now in the back. Continue cooking until outsides are crispy and meat is tender, about 5 hours, flipping every 30 minutes. Slice into small chunks.

Cook's Notes:

The moisture of the meat will mix with the rub, so when you are finished it will no longer look "dry."

This can also be made with baby back ribs. Cook time will be 4 hours 20 minutes.
