Trim/peel off silver skin from ribs if present.

Mix spices together in a small bowl then rub into both sides of the ribs, wrap in saran wrap, and then refrigerate for at least 2 hours or up to overnight.

Preheat oven to 250 degrees then line a baking sheet with foil and spray with nonstick spray.

Place ribs on top then cover tightly with more foil and bake for 3-1/2 hours (add more time if your ribs are larger then 2-1/2 lbs.)

Remove foil, drain any excess liquid from the pan, then brush BBQ sauce on top and bake for 30 more minutes, or until top is slightly caramelized.
