Step1:1 - put oil in the pot to boil. Pour crucian into the pot. Put salt. Pan fry until golden brown on both sides. Then pour cold water in (pour in the same amount of water as the fish. Or cover the fish). Add star anise, ginger and cover the pot and simmer for 15 minutes (start with high heat. Turn to low heat after boiling). 2 - open the lid of the pot, put in celery, garlic and chicken essence and cook for a short time. If it's raw, you can add ginger when you put the fish in the first place. This will remove the fishy smell. It won't stick to the pot.
