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 Ckoquettes
Ingredients
Directions
Prepare the stock
Boil the salmon remains in 1 pint of water until reduced to ½ pint for stock.
Tear the salmon flesh into shreds.
Make the sauce
In a saucepan, melt 1 tablespoon of butter, then stir in 1 tablespoon of flour to make a béchamel sauce.
Gradually add the fish stock, stirring until thick and smooth.
Stir in ½ cup of thick cream, ⅓ cup of sherry or white wine, and 2 beaten egg yolks.
Heat the mixture until it reaches boiling point but do not let it boil.
Fold in ½ pound of salmon flakes until well combined.
Shape and fry
Spread the mixture 1 inch thick on a buttered plate and refrigerate until cold.
Once chilled, cut into pieces and shape into cork or egg shapes.
Coat the shaped salmon in breadcrumbs and fry in hot oil for 2 minutes.
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 flavour and texture in the croquette filling.
- Butter
- Forms the roux with flour, giving the sauce body and a rich flavour.
- Flour
- Thickens the butter into a roux that gives the béchamel its structure.
- Egg yolks
- Enrich the sauce and help it set firm when chilled, holding the shape.
- Thick cream
- Adds richness and moisture, giving the filling a smooth, soft texture.
- Sherry or white wine
- Adds acidity and aroma that brighten the rich, creamy filling.
The step that matters
Heat the mixture without boiling. Boiling can curdle the egg yolks and cream, making the sauce grainy and thin. Gentle heat keeps it smooth and thick enough to chill and shape.
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.
