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

What each ingredient does

Codfish
Provides the main savory flavor and the flaky body of the meatballs.
Potatoes
Bind the fish and add soft, moist texture when mashed.
Butter
Adds richness and fat that softens the mixture and carries flavor.
Milk
Adds moisture that keeps the mixture tender and easy to shape.
Egg
Coats the balls so they brown and crisp when fried.

The step that matters

Soak the codfish overnight. Salted cod is very salty and must be soaked long enough to remove excess salt, since frying concentrates flavor and the fish cannot be adjusted afterward.

Swap the potato

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

  1. Capsicumfits about as well
  2. Potatothe original
  3. Asparagusfits about as well
  4. Chivefits less well

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