Serves 4. This is so easy and delicious and is a great recipe to double.

1lb pork tenderloin (1 pork tenderloin with silverskin removed)
1 tbsp Chinese rice wine or dry sherry
1 tbsp light soy sauce
2 tsp sesame oil
1 tsp cornflour
1 1/2 tbsp peanut oil

1 1/2 tbsp dried Chinese black beans, rinsed and coarsely chopped (available in Asian markets)
1 tbsp garlic, finely chopped
3 tbsp scallions (spring onions) finely chopped
1 tbsp shallots, chopped
1 1/2 tbsp light soy sauce
1 tsp sugar
1 tbsp chicken stock
1 tbsp sesame oil

Cut the pork into thin slices 1 1/2 inches long. Put the slices in a bowl and mix them well with the rice wine or dry sherry, soy sauce, sesame oil and cornflour. Leave to marinate for about 20 minutes.

Heat a wok or large frying pan until it’s very hot. Add half the oil and when it is very hot and slightly smoking, lift the pork out of the marinade with a slotted spoon, put it in the wok and quickly stir fry for about 2-3 minutes. Transfer it to a bowl at once.

Wipe the wok or pan clean, reheat it and add the rest of the oil. Quickly add the black beans, garlic, scallion (spring onions) and shallots. A few seconds later add the rest of the ingredients. bring the mixture to the boil and then return the pork to the wok or frying pan. Stir fry the entire mixture for another 5 minutes.
Turn it on to a warm serving platter and serve at once with some hot steamed rice.
