Preheat the oven to 160°C.
Put the ribs in a deep baking tin and pour hot water over them, enough to just cover them. Add the cinnamon stick, star anise, ginger and bay leaf. Cover the tin with foil then put it in the oven. Bake for 2.5 hours.
Meanwhile mix the glaze and set aside.
Drain the ribs well, let them cool, then brush them with the glaze –cover and keep in the fridge until you're ready to cook.
Heat the grill to medium-high. Grill or barbecue for 15-20 mins, turning a couple of times, until caramelised and golden. Alternatively, bake in the oven, at 200°C for 15-20 minutes.
Serve warm or at room temperature.
