1. Preheat your pellet grill to 275°F. In a small bowl, combine two tablespoons of salt, four tablespoons of coarsely ground pepper, and two teaspoons of paprika. One tablespoon of oil should be rubbed all over each rack of ribs, and the salt and seasoning combination should be evenly sprinkled on both sides.
2. Place the ribs on the grill grates, with the meat side facing upwards. Cook the ribs for 1 hour on the grill, covered.
3. In a spray bottle, pour in ⅓ cup of cider vinegar and ⅓ cup of water, then combine this mixture. After 1 hour, spritz the ribs all over with this vinegar mixture and water to dampen them. Cook the ribs for another hour, covered.
4. In a medium saucepan, pour in the ketchup, the remaining ⅓ cup of cider vinegar, ¾ cup of water, brown sugar, white vinegar, Worcestershire sauce, two teaspoons of pepper, two teaspoons of salt, spicy sauce, and two teaspoons of paprika. Cook this mixture for 2 minutes over medium heat, or until the mixture gets entirely warmed and the sugar has dissolved. Set the resulting mixture aside.
5. Examine the ribs and re-spray them with the vinegar-water mixture. They should begin to turn red due to the smoke. Cook them, keeping them covered, for 30 to 45 minutes, or until they have developed a deep red color. Spritz the ribs once again, then brush ¼ cup of the sauce over the meaty portion of each rack. Close the grill and continue to cook the ribs for an extra 15 minutes to allow the sauce to thicken.
6. Place two sheets of heavy-duty foil with a sufficient length to cover individual racks on a surface, then spread ¼ cup of sauce on half of each sheet. Place the rib racks on the saucy section of the foil, meat side down. Apply ¼ cup of sauce and a few sprays of vinegar water to the bony sides, then wrap the foil over the ribs and seal it tightly.
7. Suppose the initial layer of foil has been pierced while wrapping; add an extra layer. Place the ribs on a rimmed baking sheet and grill until done (the baking sheet should get the juices if any leak out). Cover and simmer for 2 hours, or until the meat is cooked but not coming off the bone.
8. Allow a 5-minute resting period after removing the ribs from the grill before carefully unwrapping them (be careful, so the hot steam doesn’t hurt you). Serve the ribs with the leftover sauce after slicing each rib rack into separate rib chunks.
