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

What each ingredient does

Codfish
Provides the main flavour and the flaky body of the fritters.
Potatoes
Mashed starch binds the mixture and keeps the cakes soft inside.
Eggs
Bind the mixture together so the balls hold their shape while frying.
Onion
Adds aroma and savoury sweetness once cooked into the mixture.

The step that matters

Frying in hot lard. If the lard is not hot enough, the cakes absorb grease and turn heavy before a golden crust forms. Hot fat sets the outside quickly, so the inside stays moist and the surface browns evenly.

Swap the onion

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

  1. Capsicumfits better
  2. Asparagusfits better
  3. Spinachfits better
  4. Onionthe original

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