Preheat oven to 300 F.
Mix the following ingredients in a bowl:
8 Tbsp brown sugar
1 Tbsp salt
1 Tbsp chili powder
1/4 tsp cayenne pepper
1 tsp onion powder
1 tsp garlic powder
2 Tbsp Weber - Roasted Garlic & Herb seasoning
Rub on rack of spare ribs and wrap in foil. Ideally let it sit overnight, but still is delicious if done right before baking. Place the foil-wrapped ribs in a roasting pan or on a cookie sheet to catch any drips of juice. Bake at 300 F for 2-3 hours or until the meat temperature is close to 160 F.
Place rack of ribs on grill for 10-20 minutes (until charred to your liking), basting the leftover juices in the foil back onto the ribs. While it's on the grill you can also put barbecue sauce on it if you want to. We didn't and it was still delicious!
