Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body of the croquettes and gives them their flavour.
- Milk
- Combines with butter and flour to make a gravy that moistens the fish mixture.
- Flour
- Thickens the milk and fish water into a gravy that binds the mixture together.
- Butter
- Adds fat and richness to the gravy, softening the texture of the mixture.
- Egg
- Coats the shaped croquettes so the cracker crumbs adhere and form a crust.
The step that matters
Fry the croquettes in hot lard until golden brown. If the lard is not hot enough, the croquettes absorb more fat and turn greasy, while the coating may not brown properly. Hot oil seals the crumb coating quickly, giving a crisp, golden exterior.
Swap the onion
How well each one fits the dish's main ingredients (fish, pepper, milk, butter, flour, egg, parsley):
- Potatofits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against fish, pepper, milk, butter, flour, egg, parsley. Candidates are from the same food group and used in at least 100 recipes.
