Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Hard-boiled egg yolks
Form the bulk of the balls and give them a rich, creamy body.
Raw egg yolks
Bind the mashed yolks together so the balls hold their shape.
Wheat flour
Adds starch that helps the mixture hold together and firm up slightly.

The step that matters

Drop the balls into boiling soup a few minutes before serving. Raw egg yolks in the mixture set when heated. Adding the balls to boiling soup cooks them through, while leaving them too long can make them tough or cause them to break apart.
