Get out and measure all of your ingredients.
Combine all of the rub ingredients together, except for the mustard.
Coat the ribs with a light layer of mustard.
Next, season both sides of the ribs generously with the rub mix.
Allow to marinate covered in a resealable container overnight in the fridge.
Fill the steam pot in the smoker with water and stock the smoker with wood (chunks, chips, pellets…whatever your smoker is designed for)
Smoke the ribs for about 3 hours at 225 degrees, until they reach an internal temperature of 175 degrees.
Make sure to check the water level and wood every 45-60 minutes.
Remove the ribs and wrap in butcher paper or aluminum foil.
Return to the smoker and continue to cook for 2 more hours.
After 2 hours, unwrap the ribs and return them to the smoker to cook, unwrapped, until they reach 195-203 degrees (about another hour).
Carefully remove the ribs from the smoker (letting them reach a higher temperature allows the connective tissue to break down and they are fall-off-the-bone tender)
Allow the ribs to rest for at least 15 minutes before serving.
Slice if desired.
Serve.
Enjoy every bite!
