Dark chili powder
Fresh ground black pepper
Mix together the dark chile powder, cayenne pepper, white sugar, onion powder, garlic powder, toasted cumin, fresh ground black pepper, smoked paprika, and kosher salt together to create the rub.
Cover the ribs completely with the rub. Let sit for at least 3 hours (no longer than 10) until juice begins to pool in the bottom on the tray.
Smoke the ribs for approximately 4-6 hours.
Once ribs have completed cooking, coat them with generous amounts of brown sugar and white vinegar. Top off with more brown sugar, and place in an oven for approximately 8 minutes. Slice, serve, and enjoy!
