Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fish Croquettes
Ingredients
Directions
Make the sauce
Melt the butter in a frying pan and mix with flour, cooking for a few moments.
Add enough milk to achieve a thick cream consistency.
Stir in parsley, pepper, and salt.
Form the croquettes
Combine the shredded fish and cold potato with the sauce until stiff enough to handle.
Form the mixture into croquettes using your fingers.
Dip each croquette in egg and then in cracker dust.
Fry
Fry in hot lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Mixed with melted butter to form a roux that thickens the milk into a sauce.
- Milk
- Forms the thick cream sauce that binds the fish and potato together.
- Cold fish
- Provides the main flavour and body of the croquettes.
- Cold potato
- Adds bulk and softness, helping the mixture hold together when shaped.
- Egg
- Coats the croquettes so the cracker dust adheres and browns during frying.
- Cracker dust
- Forms a crisp, browned outer crust when fried.
The step that matters
Chilling and shaping the mixture to a stiff consistency. The sauce and fish mixture must be stiff enough to handle; if it is too soft, the croquettes can fall apart in the coating or hot lard. Cold ingredients help the mixture firm up before shaping.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, flour, milk, pepper, fish, potato):
- Parsleythe original
- Nutmegfits about as well
- Capersfits less well
- Cinnamonfits less well
Fit is the average pairing score against egg, butter, flour, milk, pepper, fish, potato. Candidates are from the same food group and used in at least 100 recipes.
