Prepare a smoker for cooking between 250 and 275 degrees F. Trim the excess fat from the spareribs and cut out any sharp or cracked bones. Remove or score any silver skin.
Liberally rub the ribs with Sawdust Rub, shaking off the excess. Place the ribs in the smoker and cook, spritzing with apple juice every 30 minutes, until the fat starts to render from the surface of the ribs, about 3 hours.
Spritz a piece of heavy-duty foil with some apple juice and drizzle with about 3 tablespoons Original BBQ Sauce. Arrange the ribs on the foil, meaty-side down, and fold the foil on the ribs so that steam can escape but the juices are trapped inside. (If you multiply this recipe to do multiple racks, make sure each rack gets its own foil packet.) Put back in the smoker meaty-side down. Smoke until the meat pulls back from the bones by about 3/8 inch, another 1 to 1 1/2 hours. Let rest for 30 minutes, then slice into ribs.
Mix together the salt, pepper, brown sugar, paprika, chili powder, granulated garlic, granulated onion and cayenne in a bowl and break up any clumps by hand.
Original BBQ Sauce:
Yield:more than 1 quart
Combine the ketchup, vinegar, Worcestershire, molasses, brown sugar, hot sauce and lemon juice together in a large pot and whisk until blended. Place over medium heat and bring to a simmer, then add the chili powder, granulated garlic, onion powder, salt, pepper and cayenne. Continue to simmer 30 to 45 minutes, stirring occasionally to keep from burning.
