The method for pregnant women to eat pickled cabbage is as follows: 1. Remove the scales, gills, laparotomy and internal organs of carp, remove two pieces of fish with a knife, split the fish head and break the money bones into pieces. Wash sauerkraut and cut into sections. 2. Put the wok on the fire, heat it with a little oil, add pepper, ginger and garlic cloves to stir fry, then add sauerkraut to stir fry, add soup to boil, add fish heads and bones, and cook over high fire. Skim the foam from the noodle soup and add cooking wine to remove the fishy smell. Add refined salt and hutong noodles for later use. 3. Cut the fish into 0.3 cm long fillets, add refined salt, cooking wine, monosodium glutamate and egg white and mix well, so that the fillets are evenly covered with a layer of egg paste. 4. After the soup in the pot is tasty, shake the fish fillets into the pot. Heat hot oil in another pot, add pickled pepper powder and stir fry, then pour into the soup pot and cook 1 to 2 minutes. When the fish pieces are cooked, add monosodium glutamate and pour into the soup basin.
