Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Fish Croquettes
Ingredients
Directions
Make the base
In a saucepan, cream the flour and butter together.
Heat the milk in a double boiler until boiling, then add the flour and butter mixture.
Stir until smooth and thick, then add salt, pepper, and flaked fish.
Spread the mixture on a platter and let it cool.
Shape and fry
Shape the cooled mixture into croquettes, then roll in flour, dip in beaten eggs, and coat with breadcrumbs.
Fry the croquettes in hot fat until golden brown.
Serve
Serve on a hot dish, garnished with parsley and lemon slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the bulk and flavour of the croquette filling.
- Flour
- Thickens the butter and milk into a stiff sauce that holds the fish together.
- Milk
- Forms the liquid base of the thick sauce, giving it a smooth, creamy texture.
- Butter
- Adds fat and richness to the sauce and helps it set firm when cooled.
- Eggs
- Bind the coating so the breadcrumbs adhere and form a crisp shell.
- Breadcrumbs
- Form a crisp, browned outer crust when fried.
The step that matters
Let the mixture cool fully before shaping. A warm, loose mixture cannot hold its shape and may break apart or leak during coating and frying. Cooling lets the starch in the flour-thickened sauce set, making it firm enough to form and coat cleanly.
Swap the parsley
How well each one fits the dish's main ingredients (fish, milk, flour, butter, pepper, egg, lemon):
- Parsleythe original
- Nutmegfits about as well
- Tarragonfits less well
- Cardamomfits less well
Fit is the average pairing score against fish, milk, flour, butter, pepper, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
