This succulent pork dish can be cooked a day or two ahead of time. I like to quickly roast the cooked meat in a very hot oven just before serving to get it crispy.

Place water, sake and all other flavourings in a baking dish that will fit the pork in a single layer. Place the pork on top, skin side up. Cover and bake for 2½ hours at 160°C. (The dish can be prepared to this point and chilled for up to 48 hours.)
Increase oven temperature to 220°C, uncover the meat and roast for 10-15 minutes to crisp the skin. While the pork crisps, cook noodles according to manufacturer’s instructions, adding the green vegetables in the last 2-4 minutes (allow 2 minutes for bok choy and 4 minutes for gai lan).
Drain noodles and vegetables and divide between 6 heated serving bowls. Sprinkle with coriander and top with pork slices. Remove and discard excess fat from pork cooking juices and spoon over pork and noodles. Serves 6
