Notes on making tomato fish

1. Fish meat selection: Choose fresh fish meat with delicate meat and no peculiar smell. It is not suitable to choose fish species that are fatty or have spines.

2. Cut fish fillets: Cut the fish into thin slices. When slicing, cut along the texture of the fish to avoid affecting the taste and texture.

3. Tomato processing: Wash the tomatoes, cut them into small pieces, remove the tomato stems and skin, and set aside.

4. Fry the tomatoes: Put the cut tomatoes into the pot, add an appropriate amount of oil, and stir-fry over medium heat until the tomatoes are cooked. During this period, you need to stir constantly to prevent the tomatoes from sticking to the pot.

5. Add seasonings: Add an appropriate amount of salt, sugar, chicken essence and other seasonings to the fried tomatoes, then add an appropriate amount of water, and cook for about 10 minutes to fully integrate the seasonings and tomatoes.

6. Cook the fish fillets: Put the cut fish fillets into the pot, add an appropriate amount of salt, cooking wine, ginger slices and other seasonings, and cook over medium-low heat until the fish fillets are cooked.
