First of all, we need to prepare some ingredients, such as crucian carp, a piece of tofu and a proper amount of coriander, and then we need to prepare some cooking wine, salt, oil, ginger and a proper amount of pepper. After preparing these ingredients, we need to clean the crucian carp, because we must prepare fresh live crucian carp, so that the crucian carp soup will be more delicious. If it is soup meat made of dead fish, the meat quality will be worse. When we buy live fish, we have to clean the internal organs and scales of the fish, and the side line of the fish has to be pulled out. People who often wash fish will find that there is a black film inside the fish's stomach, and this black film must also be removed.

Cut all the tofu prepared in advance into thick slices, about two centimeters thick, then cut the ginger into thick slices, and cut all the parsley into pieces and set aside. What we need to do next is to marinate the crucian carp, and the washed crucian carp is scratched on the back for convenience. Add a proper amount of cooking wine and salt into it, then spread it evenly on the fish by hand and marinate for 15 minutes.

When the oil is hot, we put ginger in the pot. After frying, we put the fish in the pot. We always fry both sides of the fish until they are yellow. Then we can turn off the fire. In this process, we must control the heat and never fry the fish. After frying the back of the fish, you can add enough boiling water to the pot. It should be noted that boiling water must be used, otherwise the fish soup will not be white.

Boil all the water in the pot with a big fire. If the fish soup at the bottom of the pot starts to turn pale, we can add tofu. At this time, we need to continue to cook with high fire for about 10 minutes, and then add an appropriate amount of edible salt. Don't add salt too early, otherwise the soup won't turn white easily. After turning off the fire, we can add a proper amount of pepper and coriander to the pot.
