Barbecue Smoked Baby Back Ribs

1. Apply mustard as an optional binder to the pork loin back ribs.
2. Prepare the seasoning blend: combine 1/3 cup brown sugar, 2 tsp Cajun seasoning, 1 tbsp onion powder, 1 tbsp garlic powder, 1 tsp paprika, 1 tsp cayenne pepper, 1/2 tsp chili powder, 1 tbsp optional whiskey apple seasoning, and a pinch of coarse black pepper and salt.
3. Season the ribs generously with the blend.
4. Cook the ribs in a smoker for 2 hours, maintaining an internal temperature of 150-155°F. Do not touch them during this period.
5. After 2 hours, begin spraying the ribs with apple cider vinegar or water every 30 minutes.
6. Once the ribs reach an internal temperature of 180°F (approximately 3 hours total cook time), apply your favorite BBQ sauce.
7. Continue cooking until the ribs reach an internal temperature of 200-205°F, which should take around an additional 40 minutes.
