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

What each ingredient does

Mashed potatoes
Provide the bulk and soft body that holds the cakes together.
Cold boiled fish
Supplies the main flavour and flakes that give the cakes their texture.
Egg
Binds the mixture so the cakes hold their shape when fried.
Butter
Adds richness and fat, helping the cakes brown in the pan.
Milk
Adds moisture that keeps the potato mixture soft and easy to shape.

The step that matters

Fry the cakes until light brown on both sides. Frying over steady heat browns the surface through Maillard reactions while the cakes warm through. Cakes that are too hot on the outside can stay cold inside, and cakes that are shaped loosely may break apart while turning.

Swap the onion

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

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

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