You must boil them in a pan for ten minutes first -it makes then taste much nicer. Once boiled for 10 minutes coat in a bought BBQ sauce (really its not worth trying to make one) and cook at 160 C covered in foil for 40 mins, turn over ribs coat in sauce put back in oven without foil for 20 minutes -repeat process then take out of oven and leave 10 minutes before serving. IF you really want to make your own sauce then equal amounts of soy sauce, tomato puree from a tube,vinegar, honey or maple syrup, with a pinch of smoked paprika,salt pepper all shaken up in a jar is good.
