Egg Balls

Ingredients

Directions

Prepare the mixture

  1. In a bowl, mash the yolks of hard boiled eggs with a wooden spoon until smooth.

  2. Season the mixture with salt, pepper, and butter.

  3. Add enough raw egg yolk to bind the mixture.

Shape and cook

  1. Form the mixture into balls about half the size of a natural yolk.

  2. Roll each ball in egg white, then coat with flour.

  3. Poach the balls in boiling water for a few minutes until cooked.

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

What each ingredient does

Hard boiled egg yolks
Provide the main body and rich flavor of the balls once mashed smooth.
Butter
Adds fat and richness, making the mashed yolk mixture softer and more flavorful.
Raw egg yolk
Binds the mashed yolks together so the mixture holds its shape when formed.
Flour
Forms a light coating on the outside that helps the balls keep their shape while poaching.

The step that matters

Binding the mixture with raw egg yolk. Too little raw yolk leaves the mashed mixture crumbly and hard to shape, while too much makes it wet and loose. Add it gradually until the mixture just holds together.
