Recommend a practical one, no matter what kind of fish, as long as it is just washed. There is no pot of boiling water. I personally recommend boiling water in the pot. The whole fish is in the pot, and then it can be soaked immediately. After foaming, add shredded ginger, less sugar and less sugar. Cover and simmer for 5- 10 minutes, depending on the size of the fish, generally not more than 15 minutes. Finally, add salt and take out the pot. Add chopped green onion and coriander according to taste, and just eat.
