Preparation of raw materials: tenderloin 300g, a little rock sugar, a little vinegar, a little salt, a little soy sauce, a little oil consumption, a little cooking wine, a little starch and an egg.

1, first cut the tenderloin into strips about 1 cm wide, preferably not too thick, because it will be difficult to cook. Add cooking wine, egg white, oil consumption, salt and soy sauce, cover and marinate for 20 minutes.

2. Prepare sweet and sour materials for later use. The preparation method is as follows: 5 tablespoons of water, 4 tablespoons of vinegar, 3 tablespoons of sugar, 2 tablespoons of soy sauce, and cooking wine 1 tablespoon are evenly mixed for use.

3. Mix a bowl of water, add proper amount of starch and flour, stir into paste, and pour into the marinated tenderloin and mix well.

4. Pour the oil in a hot pot, cook until it is 7% mature, and add the tenderloin. Because it is cooking at home, it is recommended to save fuel. When cooking, you can pour a little more oil than usual, fry two loins in the middle, and control the oil when the surface is brown.

5. The fish fillets are completely fried for the first time. After controlling the oil, pour in the fried fish fillets, fry them again, and take them out.

6, put oil in the pot, pour in the sweet and sour ingredients prepared before, stir fry until bubbling, and pour in the tenderloin and stir fry evenly. You can sprinkle some white sesame seeds in the pot.
