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 gives the balls body and a soft, tender interior.
Codfish
Adds savoury flavour and a flaky texture that blends into the mashed potato.
Egg
Binds the mixture so the balls hold their shape while frying.
Cream or milk
Adds moisture and richness, keeping the mash soft and smooth.
Butter
Adds fat for richness and flavour, and helps the mixture stay tender.

The step that matters

Beat the mixture until well combined. Thorough mixing spreads the egg, fat and liquid evenly through the mash, so the balls hold together and cook uniformly rather than crumbling or turning out patchy.

Swap the potato

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

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

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