Heat the smoker to 250-275F degrees. Place the ribs on the smoker and smoke, spritzing every hour with apple cider vinegar, until they reach an internal temperature of 203F degrees, about 6 hours. Remove from the smoker. Wrap in foil, and let rest for 30 minutes.
You can use kosher salt, instead of sea salt and white or brown sugar in place of the coconut palm sugar.
