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

What each ingredient does

Hard-boiled eggs
Their mashed yolks form the body of the soup balls.
Raw egg yolk
Binds the mashed yolks so the mixture holds its shape.
Flour
Adds a little body to the mixture, helping the balls hold together.

The step that matters

Forming the balls. The mixture must be firm enough to hold its shape. Too much moisture or too little binder can make the balls fall apart in the boiling water, so shape them gently and firmly.

Swap the parsley

How well each one fits the dish's main ingredients (egg, flour, pepper):

  1. Turmericfits about as well
  2. Parsleythe original
  3. Nutmegfits about as well
  4. Jalapenofits about as well

Fit is the average pairing score against egg, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
