Preparation method:

1. Remove the head and internal organs of the Spanish mackerel and cut into large pieces.

2. Use vegetable oil to fry the onions until they are raw, add ginger slices, peppercorns, aniseed, fennel, bay leaves, tomatoes, tomato sauce, sugar, salt, light soy sauce, and oyster sauce to taste. Stir-fry over medium-low heat to form a sauce (if it feels a little dry, add a little boiling water).

3. Put the prepared sauce and fish pieces into the pressure cooker, add cooking wine and vinegar.

4. The electric pressure cooker takes 40-50 minutes. If the pot has a lot of fish, you can increase the time appropriately.

5. After the fish is cooked, soak it in the soup for about a day.

6. Eat it directly after taking it out of the pot.
