Steps of making pickled fish:
1. Chop pickled peppers and ginger, and slice sauerkraut for later use.
2. Pour oil into the pot, add chopped pickled peppers, pickled ginger and pickled cabbage, stir fry, add boiling water, and add fish heads and bones for slow stew. After the water is boiled, simmer it with low heat.
3. Marinate the fish fillets with starch and egg white.
4. After the fish bones and fish heads are cooked, put the pot into a big bowl with a colander. Boil the soup in the pot and add the fish. Don't stir. When starch wraps meat, you can stir it and add chicken essence to improve the taste. Pour the soup into the soup basin and sprinkle with garlic and pepper.
5. Heat the oil in the pot to smoke, pour it on garlic and pepper, and add seasoning according to your own taste.
