Remove about 14 cup of the cold chicken broth and blend it in a small bowl or cup with cornstarch
Bring the remaining broth to a boil and when it is simmering stir in salt to taste monosodium glutamate and the well blended cornstarch mixture
When the soup has thickened and cooked for about 1 minute turn off heat Immediately but slowly start adding the egg in a thin stream stirring constantly in a circular fashion so that the egg forms thin shreds in the hot broth
