Rinse the ribs with hot water to remove the blood from them, and then cook them with cold water. Bring the fire to the boil and simmer it gently. Be careful. Don't let the water run out. Slice the radish and mushrooms, wait for the bones to stew for about an hour and a half, add the radish and mushrooms and stew for another half an hour. Stewed ribs juice is the best, no need to add other seasonings, just add some salt.
