My favorite things.... Rum and Coke.  Ribs..

ngredients – Ribs (serves 4)

2 racks large beef back ribs
1 tsp salt
½ tsp freshly ground pepper
1 onion, peeled and quartered
6 cloves garlic crushed
8 cups (2 litres) cola
Ingredients – Sauce

1 tsp olive oil
1 onion minced
1 clove garlic, minced
1 tsp ground cumin
1 tsp chilli powder
¾ cup tomato sauce
1/3 cup dark rum
¼ cup packed brown sugar
¼ cup cider vinegar
1 tbsp Dijon mustard
1 tbsp Worcestershire sauce
Dash Tabasco Sauce

1. For the ribs, trim any visible fat from ribs and remove membrane from underside if attached. Season both sides with salt and pepper and place meat-side down in large baking dish. Arrange onion and garlic evenly around ribs. Pour enough cola to cover ribs completely. Bake for 3 hours at 200°F(95°C). Remove from oven and allow ribs to come to room temperature in cooking liquid, about 1 1/2 hours.
2. Meanwhile, to make the sauce, heat oil in small saucepan over medium heat. Add onion, garlic, cumin and chili powder and cook for 5 minutes, stirring constantly. Add ketchup, rum, brown sugar, vinegar, mustard, Worcestershire sauce and hot pepper sauce and simmer for 15 minutes.
3. Preheat grill to low.
4. Place ribs meat-side down on grill and close lid. Cook, turning occasionally, until meat is browned and caramelized, about 30 to 45 minutes, or until tender and bones are exposed at ends. With 10 minutes remaining, brush ribs with barbecue sauce. Cut into 3-rib pieces and serve.
