Preheat the oven to 200°C and fry the ribs on a rack for half an hour.
Meanwhile, heat maple syrup, chili sauce, Worcester sauce, red wine vinegar, onion, mustard powder, some salt and pepper in a pot and cook for 5 minutes.
Remove the ribs from the grate and lower the temperature to 180°C.
Place the meat in a roasting pot and spread the sauce mixture over it. Cook uncovered for another 45 minutes, brushing with gravy over and over again.
