First, wash the ribs with water to remove blood foam. In this step, cooking wine and ginger can be added to remove the fishy smell. Then, after blanching, put the ribs in a pot with hot water. First, ribs are cooked without salt. After the meat is rotten, add potatoes, fungus and ribs. Then cook the ribs for about half an hour, and add salt about ten minutes before taking out the pot.
