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

What each ingredient does

Boiled liver
Forms the main body of the balls, giving them a rich, meaty flavor.
Breadcrumbs
Absorb moisture and help the mixture hold its shape while frying.
Egg
Binds the mixture together and forms a coating that browns when fried.
Onion
Adds sweetness and aroma to the mixture once cooked.

The step that matters

Fry in boiling fat until golden brown. The fat must be hot enough to brown the egg coating quickly. If it is too cool, the balls absorb grease and turn soggy and may break apart before the interior is cooked through.

Swap the onion

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

  1. Capsicumfits better
  2. Asparagusfits better
  3. Spinachfits better
  4. Onionthe original

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