Step 1

Heat a wok until smoking and add two tablespoons of the groundnut oil, then fry the aubergine slices with a splash of water for 3-4 minutes, or until softened and golden-brown all over. Transfer to a plate and set aside.

Step 2

Wipe away the excess oil from the wok, reheat and add the remaining groundnut oil. Heat until smoking. Stir fry the garlic, ginger and chilli for a few seconds, then add the minced pork. Stir fry for one minute, then add the rice wine or sherry. Cook for 3-4 minutes, or until browned, then add the chilli bean sauce and hot chicken stock. Return the aubergines to the wok and add the pak choi.

Step 3

Season, to taste, with the vinegar and sesame oil and bring to the boil. Cook for 3-4 minutes, or until the pork is cooked through, then stir in the spring onions. Add the cornflour paste and stir until the liquid has thickened.

Step 4

Spoon the fragrant pork and aubergines into a serving bowl and serve immediately.
