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 rich, crumbly body and flavor to the mixture.
Potato
Adds bulk and moisture, helping the mixture hold together when shaped.
Raw egg yolk
Binds the mixture so the balls keep their shape.

The step that matters

Dropping the balls into soup just before serving. The balls are delicate and can break apart or turn dense if they sit too long in hot liquid. Adding them at the last moment keeps them intact and tender.

Swap the potato

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

  1. Carrotfits better
  2. Capsicumfits better
  3. Spinachfits better
  4. Potatothe original

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