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

What each ingredient does

Hard-boiled eggs
Provide the bulk and main body of the filling.
Raw egg yolks
Bind the mixture as their proteins set with heat, and add richness.
Flour
Forms a dry coating that keeps the balls from sticking to the hands.

The step that matters

Boil the balls in gravy for a few minutes. The raw yolks set as they heat and act as the binder holding the balls together. A gentle simmer lets them set firmly, while a hard rolling boil can crack or break the balls apart.

Swap the white pepper

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

  1. Jalapenofits better
  2. Capersfits better
  3. Nutmegfits better
  4. White pepperthe original

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