Why it works: Parsley and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 3,737 recipes mention both. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Piquante Sauce
Ingredients
Directions
Make the sauce
In a saucepan, combine sweet herbs, parsley, shallots, bay leaves, mace, cloves, salt, and vinegar.
Cook until nearly dry, then add brown stock and stew for 15 minutes.
In another pan, melt butter, add flour, and strained stock; bring to a boil.
Finish and serve
Season with cayenne and serve.
Optionally, stir in chopped gherkins, capers, or lemon juice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides acidity that sharpens the sauce and gives it its piquant character.
- Butter
- Adds richness and fat that gives the sauce a smooth, rounded mouthfeel.
- Flour
- Thickens the stock, giving the sauce body.
- Brown stock
- Forms the savoury liquid base that carries the flavour of the sauce.
The step that matters
Cook the herb and vinegar mixture until nearly dry. Reducing the vinegar concentrates its acidity and aromatics before the stock is added, so the sauce has a sharp, layered flavour rather than a diluted one.

- Macethe original
Fit is the average pairing score against parsley, shallot, clove, vinegar, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
