Ingredients:
500 grams (0.11 lb) of pork fillet
50 grams (2 3/4 tbsp) soy sauce
20 grams (1 3/4 tbsp) cooking wine
50 grams (3 tbsp) sugar
3 grams (1/2 tsp) salt
30 grams (2 tbsp) vinegar
10 grams (2 tsp) mixture of cornstarch and water
100 grams (7 tbsp) cooking oil
10 grams (1/3 oz) sectioned scallions
10 grams (1/3 oz) sliced ginger
100 grams (8 tbsp) dry cornstarch
50 grams (3 tbsp) water

Directions:

1. Cut the fillet into chunks 5 cm (2 inches) long and 4 cm (1.6 inches) wide and mix with 5 g (1/6 oz) of scallions and ginger each, 1 g (1/6 tsp) of salt and 10 g (2 tsp) of cooking wine, and marinate for 10 minutes.

2. Dust the marinated chunks of meat with dry cornstarch.

3. Heat the oil to 180-200oC (355-390oF) and deep-fry the chunks of meat, piece by piece, until they are done. Take out and drain off the oil.

4. Keep 50 g (3 1/2 tbsp) of the oil in the wok and add the cooking wine, soy sauce, sugar, MSG and salt and water, and bring to boiling point. Add the vinegar and thicken the soup with the mixture of cornstarch and water. Put in the deep-fried fillet and turn several times to allow the ingredients to be fully absorbed into the meat and gravy. Take out and serve.

Features: The color of the meat is brown and the gravy is shiny.

Taste: Crispy, tender, sour and sweet to the right taste.
