Why it works: Parsley and cucumber match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,564 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Salmon Croquettes
Ingredients
Directions
Make the sauce base
Boil the salmon remains in 1 pint of water until reduced to ½ pint for stock.
Tear the salmon flesh into shreds.
In a saucepan, melt the butter and stir in the flour to make a béchamel sauce using the fish stock.
Once thick and smooth, add the cream, sherry, and beaten egg yolks, stirring gently.
Heat until just boiling, then fold in the salmon flakes.
Chill and shape
Spread the mixture an inch thick on a buttered plate and refrigerate until cold.
Shape the cold mixture into cork or egg shapes, then crumb them.
Fry and serve
Fry in very hot fat for 2 minutes until golden.
Garnish with fried parsley and serve with cucumber salad.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon flakes
- Provide the main fish body and flavour of the croquette filling.
- Flour
- Thickens the butter and stock into a béchamel that holds the filling together.
- Egg yolks
- Enrich the sauce and help it set firm when chilled and fried.
- Thick cream
- Adds moisture and richness, giving the filling a softer, smoother texture.
- Butter
- Adds fat and flavour to the roux that starts the béchamel sauce.
The step that matters
Chilling the mixture until cold. The filling must be fully cold and firm before shaping, or it stays soft and the croquettes can break or leak in the hot fat.
Swap the parsley
How well each one fits the dish's main ingredients (salmon, butter, flour, cream, sherry, egg, cucumber):
- Capersfits better
- Nutmegfits better
- Tarragonfits about as well
- Parsleythe original
Fit is the average pairing score against salmon, butter, flour, cream, sherry, egg, cucumber. Candidates are from the same food group and used in at least 100 recipes.
