Sprinkle ribs all over with kosher salt and refrigerate (covered) overnight.
Mix all rub ingredients and sprinkle over all surfaces of ribs.
Cook ribs in a smoker at 225 degrees until internal temperature of 200-205 degrees is reached, 5-7 hours.
Let rest, covered loosely for 20-30 minutes before serving.
Notes
The amount of ribs and rub are for 2.5 pounds of ribs, which will yield approximately just less than 1 pound of meat. If smoking more increase accordingly.
