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
Prepare the stock
Boil the salmon remains in 1 cup of water until reduced to ½ cup for stock.
Make the custard base
Tear the salmon flesh into shreds.
In a saucepan, melt the butter, then stir in the flour to make a roux.
Gradually add the fish stock, stirring until thick and smooth.
Remove from heat and stir in the cream, sherry, and beaten egg yolks.
Heat gently until just boiling, then add the salmon flakes.
Spread the mixture 1 inch thick on a buttered plate and refrigerate until cold.
Shape and serve
Once chilled, cut into pieces and shape into cork‑like forms.
Coat in breadcrumbs and fry in hot oil 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
- Provides the main flesh and flavour that the croquettes are built around.
- Butter
- Enriches the flavour and, with flour, forms the roux that thickens the base.
- Flour
- Thickens the stock through a roux, giving the mixture body so it can set.
- Thick cream
- Adds moisture and richness, giving a softer, smoother texture to the mixture.
- Egg yolks
- Add richness and, when gently heated, help thicken and bind the mixture.
- Sherry or white wine
- Adds acidity and aroma that balance the richness of the cream and fish.
The step that matters
Chilling the mixture until fully cold. The mixture must set firm before shaping. Egg yolks and starch thicken as they cool, and if it is not fully chilled the forms will be soft and may break or collapse in the hot oil.
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.
