Choose a small and easy-to-taste fish, wash it, add a little salt and cooking wine for a while to get rid of the fishy smell and draw patterns on the fish.

Chop onion, ginger and garlic, dice red pepper, and prepare some minced meat.

Bring the pan to a boil, fry the fish on both sides golden, and put it on a plate for later use.

Stir-fry the bean paste with the remaining oil, add minced garlic and Jiang Mo, and stir-fry.

Then stir-fry the minced meat for a while, put the fish and cooking wine, submerge the fish with water, put a little soy sauce and vinegar, boil over high fire, simmer slowly with low fire, and let the taste of the soup enter the fish, which will be more delicious.

When the soup is almost the same, add diced red pepper, add some sugar and monosodium glutamate to dry, sprinkle with chopped green onion and serve.

Matters needing attention in the purchase of piranha:

When we buy fish, we should first choose the fish that is alive and kicking, because if the fish is alive and kicking, it means that the fish is healthy, and when we buy fish, we should try to choose the fish with complete scales and no defects, because this kind of fish is relatively fresh.

When we buy fish, we should also pay attention to the gills. If the gills are bright red, it means that the fish is fresh and not anoxic. If the gills are dark red, it means that the fish is somewhat anoxic and not too fresh. After the fish dies, the color of the gills will turn white.

When we buy fish, we should try to choose live fish. If we find bugs on the fish or other places when we buy live fish, we'd better not buy such fish, because there may be parasites such as schistosomiasis on such fish.
