Preheat the oven to 200°F. Remove membrane from ribs. Rinse and pat the ribs dry.
Mix all the dry ingredients in a bowl and rub evenly along ribs. Place ribs, curved side down, on a shallow rack on a foil-lined baking sheet. Combine apple juice and liquid smoke and place in a clean spray bottle (get a new one, don’t use one that has had chemicals in it!).
Every hour, remove from the oven and mist gently with the apple juice and liquid smoke mixture. After 6 hours, remove and place on a high-heat grill for 2-3 minutes per side to get a nice crust on them.
Alternatively, for a weeknight meal, cook in a 325°F oven for about 45-60 minutes, until the internal temperature of the meat is 165°F.
Notes
*Use a brand with minimal ingredients, i.e. water and smoke; I used Lazy Kettle brand.
