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

What each ingredient does

Mashed potatoes
Adds body and moisture, helping the mixture hold together while staying soft inside.
Egg yolk
Binds the mixture so the patties hold their shape when fried.
Whole egg
Adds structure as it sets, binding the fish and potato together.
Butter
Adds richness and fat, contributing flavour and a tender texture.
Breadcrumbs
Form a crisp coating that browns when fried.

The step that matters

Frying in hot fat. If the fat is not hot enough, the patties absorb more oil and turn greasy before the coating browns. Hot fat quickly sets and browns the crumb crust while the interior heats through.

Swap the potato

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

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

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