Cajun-Style Barbecued Baby Back Ribs

1 rack pork baby back ribs
DRY RUB:--
1 tbsp paprika
½ tbsp salt
½ tbsp garlic powder
1 tsp NY Cut pepper
¾ tsp onion powder
¾ tsp dried leaf oregano
¾ tsp dried thyme
½ tsp cayenne pepper
½ tsp cajun seasoning
¼ tsp crushed chilli flakes
¼ cup (packed) dark brown sugar
MOP SAUCE:--
½ cup SIDS SMOKEY GARLIC SAUCE
½ tsp molasses
¼ tsp cajun seasoning
Pinch of onion powder

Remove sinew (silver skin) from back of ribs. Place rack of ribs, meaty side up, onto a large sheet of heavy duty foil.
In small bowl, mix very well the dry rub ingredients. Pat on a little over half onto the top side of the ribs. Turn ribs over, and pat on rest of rub. Bring up sides of foil and roll down. Roll up each end. BE CAREFUL not to tear or make holes in foil. Place onto a foil-lined baking sheet.
Bake now, or let let marinate for several hours or overnight.
Preheat oven to 150°C.
Put ribs into oven and bake for 2½ hours. Remove from oven.
Turn oven up to 175°C.
Carefully open foil and move ribs to a new foil-lined baking sheet bones side-up.
In small bowl, whisk together SIDS SMOKEY GARLIC SAUCE and all sauce ingredients. Coat bone side with a little less than half of the sauce.
When oven has reached 175°C, put into oven and bake for 10-12 minutes.
Remove from oven, turn ribs over, coat with rest of sauce.
Put back into oven and bake another 5-10 minutes.
Cut into serving-sized pieces.
