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

What each ingredient does

Salt codfish
Provides the main flavor and savory body of the fish balls.
Potatoes
Adds starch and bulk that holds the mixture together and keeps it soft inside.
Egg
Binds the mixture and helps it set and stay light when beaten.
Butter
Adds fat for richness and a softer, more tender texture.

The step that matters

Drain and shake over the fire until dry. Excess water left in the fish and potatoes makes the mixture loose and soggy, so the balls may not hold their shape or fry well. Drying off the moisture helps the mixture stay firm.

Swap the potato

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

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

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