Blanch the cut spareribs in boiling salted water for 10 minutes. Drain well and discard the water. Heat a wok over high heat until it is hot, then add oil. When the oil is hot and slightly smoking, add the garlic, ginger and spring onions and stir-fry for 1 minute. Then add the spareribs and stir-fry for 4 minutes or until they are slightly browned. Add the rest of the ingredients and bring the mixture to a boil. Transfer the contents to a flameproof casserole. Cover and simmer 40 minutes or until the meat on the ribs is very tender. Serve at once as part of a chinese meal.
