Why it works: Shallot and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 405 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Piquante Sauce
Ingredients
Directions
In a small saucepan, combine shallots, gherkins, capers, vinegar, thyme, bay leaf, and mignonette pepper.
Bring to a boil and reduce the vinegar to a third of its original quantity.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French vinegar
- Its acidity is concentrated by reduction, giving the sauce its sharp, piquant character.
- Shallots
- Provide a mild aromatic sweetness and savoury base as they soften in the reduction.
- Espagnole sauce
- Supplies the body and thickness of the sauce as the base for the finished dish.
- Blond of veal
- Adds rich savoury depth and body to the sauce.
The step that matters
Reducing the vinegar. Vinegar must reduce to about a third of its volume so its acidity concentrates and the flavour stays sharp rather than thin. Under-reducing leaves the sauce weak and watery once the Espagnole and veal are added.
Swap the thyme
How well each one fits the dish's main ingredients (shallot, capers, vinegar, pepper, sauce, veal):
- Tarragonfits better
- Parsleyfits better
- Thymethe original
- Marjoramfits about as well
Fit is the average pairing score against shallot, capers, vinegar, pepper, sauce, veal. Candidates are from the same food group and used in at least 100 recipes.
