Prepare spare ribs by cutting to a St. Louis Cut and then remove the membrane.
Combine rub ingredients in the specified quantities and liberally apply to both sides of the ribs.
Set smoker to 225F.
Once smoker is at 225F, put your ribs on the smoker and smoke the ribs for 2 hours.
After 2 hours, take ribs off the smoker and wrap in aluminum foil - meat side down.
Before completely wrapping, prepare your wrap liquid. Combine the ingredients and then heat for 10 seconds in the microwave. Then pour the liquid into the wrap. Then seal the wrap so that no steam can escape. Return the wrapped ribs to the smoker
Smoke the ribs for 2 more hours.
After 2 hours, open the wrap and place the ribs on the smoker meat side up.
Take your BBQ sauce and apply to the surface of the ribs. Use a basting brush to paint the surface of the ribs with the BBQ sauce. Smoke for 1 more hour.
After the hour, take the ribs off the smoker to rest on a cutting board for 15 minutes. After resting, slice between the bones and enjoy!
