These Maple Cayenne Glazed Ribs are smoked low and slow over applewood, then finished with a sticky homemade glaze made with maple syrup, honey, vinegar, and cayenne.
Remove the membrane from the ribs and trim away any silver skin. Pat the ribs dry, then coat them with mustard.
Combine the brown sugar, black pepper, kosher salt, smoked paprika, garlic powder, onion powder, mustard powder, and cayenne. Generously season both sides of the ribs.
Preheat the smoker to 225°F and add applewood for smoke.
Place the ribs on the smoker and cook for 3–4 hours. After the first 90 minutes, spritz with apple cider vinegar. Continue spritzing every 45–60 minutes.
Once the bark is set and the ribs reach about 160–170°F internally, remove them from the smoker.
Spritz the inside of three sheets of butcher paper with apple cider vinegar. Place one rack of ribs bone-side up on each sheet. Add 3 tablespoons of butter to each rack and wrap tightly.
Return the wrapped ribs to the smoker and cook for another 90–120 minutes. Keep the smoker at 225°F or increase it to 250°F if needed.
Near the end of the wrapped cooking time, combine the maple syrup, ketchup, maple vinegar, white vinegar, honey, cayenne, and 3 tablespoons butter in a saucepan over medium heat.
Simmer the glaze for 6–8 minutes, then remove it from the heat and allow it to cool slightly.
Remove the ribs from the smoker and open the butcher paper, leaving the ribs sitting on the paper. Brush the ribs generously with the maple cayenne glaze.
Return the ribs to the smoker uncovered for 25–30 minutes to set the glaze.
Remove the ribs from the smoker and let them rest for 30 minutes before slicing and serving.
