Combine all dry ingredients in a bowl. Pat ribs dry with paper towel. Then coat ribs all over with spice mixture, wrap tightly in foil, place on baking sheet and set in fridge overnight.
Preheat oven to 325 degrees F. When oven’s ready, place ribs, still wrapped in foil, on baking sheet in oven for 2.5 hours.
Remove from oven. Let ribs cool, discarding foil and accumulated juices.
Combine remaining ingredients to make Sriracha BBQ Sauce. Generously brush ribs with sauce all over and place on heated grill for 5-10 minutes or until slightly charred in spots. Enjoy!
Recipe Notes
The baking step can be done a day in advance. Just store in refrigerator until ready to grill.
