Wheat flour
Adds body to the mixture so the balls hold their shape.
Raw egg yolks
Bind the mixture together and help it hold its shape.

The step that matters

Drop the balls into boiling soup a few minutes before serving. The balls are fragile and can break apart if the soup is not at a full boil, or if they are left to simmer too long. Adding them shortly before serving keeps them intact and tender.
