Char siu pork on steamed pak choi

Method

1. Cut slashes into the pork. Combine marinade ingredients and marinate the pork for as long as possible, ideally overnight.
2. Preheat oven to 200°C/fan 180°C/gas 6. Remove pork from marinade and place on a rack over a roasting tin. Reserve marinade. Pour hot water into the tin to fill halfway. Roast for 20 minutes, turn the pork over and brush well with some marinade. Reduce the oven to 180°C/fan 160°C/gas 4 and roast for 20 minutes more. Turn off the oven but leave the pork inside, covered with foil, to keep hot.
3. Bring a little water to the boil in a wok or saucepan – make sure a steamer will fit in the wok without the base being submerged in water. Put pak choi in the steamer, cover and steam for 1½-2 minutes (3-4 minutes if using larger pak choi).
4. Bring remaining marinade to the boil, then remove from the heat.
5. Arrange the pak choi on plates. Slice the pork and place on the pak choi. Drizzle with the hot sauce and garnish with the spring onion.
