Preheat the oven to 300°F (150°C).

Remove the membrane from the back of the ribs for better tenderness.

In a mixing bowl, combine all dry rub ingredients and mix well.

Rub the mixture generously over both sides of the ribs.

Place the ribs on a baking sheet lined with aluminum foil, bone side down.

Cover the ribs tightly with another piece of aluminum foil.

Bake in the preheated oven for 2.5 to 3 hours, until tender.

Remove the ribs from the oven and discard the top foil.

Brush barbecue sauce generously over the ribs.

Increase the oven temperature to 400°F (200°C) and bake uncovered for an additional 30 minutes.

Let the ribs rest for 10 minutes before slicing and serving.
