2 tbsp tomato puree
1 tbsp cornstarch
Juice of 2 limes
2 tbsp maple syrup
2 garlic cloves, crushed
1/2 tsp dried chili flakes
1/2 tsp salt
1 1/2 pound pork ribs

Mix together the tomato puree and cornstarch to make a pasta. Stir in the lime juice, maple syrup, garlic, chili, and salt.
Preheat the broiler to medium, rub the mixture into the pork ribs then arrange on a broiler rack.
Cook under the broiler or on a barbecue for 30 minutes, turning occasionally, until well cooked and nicely browned. You can also cook them in the oven to 375 F, pop the ribs on a wire rack, place on a baking tray and cook for 40-45 minutes.
