  • Smoker
  • Foil
  • Saucepan
  • Meat thermometer (optional)

Ingredients
  

For the Kansas City Ribs:

  • 2 racks pork spare ribs or St. Louis-style ribs about 2.5-3 lbs each
  • Yellow mustard for binder, optional
  • Apple cider vinegar for spritzing
  • Wood chips or chunks (hickory, apple, or cherry) if smoking

For the Dry Rub (make a larger batch to have extra!):

  • 1/2 cup brown sugar packed
  • 1/4 cup paprika
  • 2 tablespoons salt
  • 2 tablespoons black pepper
  • 1 tablespoon garlic powder
  • 1 tablespoon onion powder
  • 1 tablespoon chili powder
  • 1 teaspoon cayenne pepper adjust to taste

For the Smoky Mesquite BBQ Sauce:

  • 2 cups ketchup
  • 1/2 cup apple cider vinegar
  • 1/2 cup packed brown sugar
  • 1/4 cup molasses
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon liquid smoke recommended
  • 2 tablespoons smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon cayenne pepper optional
  • Salt and black pepper to taste

Instructions
 

Prepare the Ribs:

  • Remove the membrane from the back of each rack of ribs using a butter knife and paper towel.
  • Optionally, lightly coat the ribs with yellow mustard to act as a binder for the rub.
  • Generously apply the dry rub to all sides of the ribs, pressing it in firmly.
  • Wrap the ribs tightly in plastic wrap and refrigerate for at least 2 hours, or preferably overnight.

Cook the Ribs (Smoker Method - Recommended for "Smoky Mesquite"):

  • Preheat your smoker to 225-250°F (107-121°C).
  • Place ribs directly on the grates and smoke for 3 hours, spritzing with apple cider vinegar every hour.
  • After 3 hours, wrap the ribs tightly in foil with a splash of apple cider vinegar or apple juice and return to the smoker for another 2 hours.
  • Unwrap the ribs and return them to the smoker for the final hour, basting with the Smoky Mesquite BBQ Sauce during the last 30 minutes with multiple thin coats.

Prepare the Smoky Mesquite BBQ Sauce:

  • Combine all sauce ingredients in a saucepan and bring to a simmer over medium-low heat.
  • Stir occasionally for 15-20 minutes until slightly thickened and flavors meld, then taste and adjust seasoning.

Finish and Rest:

  • Once ribs are tender (internal temperature around 195-203°F or when a toothpick slides easily), remove them from heat.
  • Tent with foil and let rest for 10-15 minutes before slicing.
  • Slice ribs between the bones and brush generously with extra Smoky Mesquite BBQ Sauce before serving.

Serve and Enjoy:

  • Serve immediately with classic barbecue sides like coleslaw, baked beans, or cornbread, and don't forget plenty of napkins!

Notes

For best results, prepare the dry rub and refrigerate the ribs overnight to allow the flavors to penetrate deeply. Adjust cayenne pepper in both the rub and sauce to your preferred spice level. A good meat thermometer is highly recommended to ensure the ribs are cooked to perfection.
