Preheat the oven to Gas Mark 4, 180°C, fan 160°C. Place a large frying pan over a low heat, add the duck legs and brown on all sides, rendering out as much fat as possible. This will take about 10 minutes. Drain off the fat, leaving just a couple of tbsps in the pan.
Add the ginger, garlic and chilli to the pan and sauté for about 2 minutes, until softened. Add the soy, tomatoes and a splash of water and bring to the boil for a few minutes.
Rub the five spice into the skin of the duck legs, then place them in a deep baking dish. Pour over the sauce and drizzle with honey. Cover with foil and bake for 1 hour. Add the cabbage to the dish for the last 10 minutes.
Remove the foil and turn the heat up to Gas Mark 6, 200°C, fan 180°C. Cook for about 10 minutes, until the duck is crisp and cooked through. Serve with mash, or steamed rice, and watercress salad.
