Take the fish to remove the internal organs, scrape off the white film on the body, wash it and cut it into 6cm small pieces for use, green onions and ginger slices.
Use a kitchen napkin to remove excess water from the fish, roll the fish in the flour, and evenly apply a layer of flour.
Put oil in the pan, heat the oil to 6-7% in the middle heat, fry the fish with a portion of the fish, and then fry until the other side is golden (about 6 minutes).
Pour the oil into the wok, stir the scallion with the onion, garlic and ginger. Pour the fried octopus, add the sugar, scented wine, soy sauce and salt and continue to stir.
Pour the right amount of warm water into the pan, cook until the water costs, cover the lid and cook for a while. When the water is dry quickly, add the balsamic vinegar and stir well to serve.
If you don't like to wrap the fish with flour, you can use eggs instead; Don't be too violent when frying the fish, otherwise the fish will be broken and not very beautiful. The white powder on the fish is especially liked by some people, so you don't have to remove it. However, it will be more embarrassing, not afraid of swearing, please be brave to eat, no poison.
