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

What each ingredient does

Codfish
Provides the main flavor and body of the cakes.
Potatoes
Add starch and bulk so the mixture holds together and stays soft inside.
Egg
Binds the mixture so the cakes hold their shape while frying.
Milk or cream
Adds moisture and softness to the mixture.
Butter
Adds fat for richness and a tender texture.

The step that matters

Beat the mixture until very light. Beating incorporates air and works the potato starch, which lightens the texture of the mixture. Thorough beating helps the cakes stay tender rather than dense.

Swap the potato

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

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

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