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

What each ingredient does

Potatoes
Provide the starchy bulk that binds the mixture and gives the cakes a soft interior.
Codfish
Supplies the flaky fish flavour and texture that defines the cakes.
Butter
Adds richness and fat, contributing moisture and flavour to the mixture.
Egg
Acts as a binder that helps hold the mashed mixture together in shaped cakes.

The step that matters

Mash and mix the potatoes, fish, butter and egg. The mixture must be mashed smooth and evenly combined so the cakes hold their shape. Excess water left from boiling can make the mixture soggy and cause the cakes to fall apart while frying.

Swap the potato

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

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

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