METHOD: -
Combine the Rub ingredients and rub onto both sides of the ribs. Set aside to marinate for 20 mins (or overnight)
Preheat oven to 160°C
Place ribs on a tray in a single layer. Pour apple cider underneath the ribs, cover with foil then bake for 1 hour 30 mins or until the meat is tender.
Remove from oven, turn up to 180°C. Remove foil, drizzle with olive oil, then return ribs to oven for 15 mins or until rub becomes nice and crusty.
Line a new tray with foil then baking paper.
Remove ribs from oven, transfer to lined tray. Pour any juices from tray over the ribs.
Flip ribs so the bonier side is up. Slather with Barbecue Sauce, then bake 10 mins.
Remove from oven, then turn ribs over so the meaty side is up. Slather with Barbecue Sauce, bake 5 mins. Repeat 2 or 3 more times until you've got a thick glaze on the ribs.
Cut ribs into individual or multiple rib portions and serve with remaining Barbecue Sauce.
To Make Homemade BBQ Sauce
Place all ingredients in a saucepan and simmer over medium heat, stirring occasionally, for 45 mins or until thickened.
Adjust to taste: sweetness with brown sugar / honey, salt and sour with vinegar. Use for glazing ribs and as a sauce for serving.
