Reserve ¾ cup of the chicken broth (it will later be mixed with the cornstarch). Pour the rest of the broth into a saucepan.
Stir in ginger, salt, and green onions. Bring to a boil. While bringing to a boil combine the corn starch with the reserved chicken broth and mix well. Set aside.
In a bowl whisk eggs and the egg yolk together with a fork.
Slowly drizzle the egg a little at a time with a fork into the boiling broth. The egg will cook right away.
Pour the cornstarch mixture into the broth and stir until its mixed well.
