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

What each ingredient does

Cold boiled fish
Provides the main flesh and flavour of the croquettes.
Mashed potatoes
Adds bulk and softness, helping the mixture hold together while moist.
Egg
Binds the mixture so the croquettes keep their shape.
Butter
Adds richness and moisture to the filling.
Hot milk
Softens the mixture and keeps the potato filling moist.

The step that matters

Let the mixture cool before shaping. A warm, soft mixture is too loose to hold its shape, so it can fall apart or stick to the hands. Cooling lets the starch and egg set slightly, firming the mixture so the balls keep their form in the hot fat.

Swap the parsley

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

  1. Parsleythe original
  2. Nutmegfits about as well
  3. Thymefits less well
  4. Dillfits less well

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