Why it works: Capers and shallot 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 ↓
Sauce Tartare
Ingredients
Directions
Make the emulsion
Mix mustard, sugar, salt, and cayenne; add yolks of eggs, and stir until thoroughly mixed, setting bowl in pan of ice-water.
Add oil, at first drop by drop, stirring with a wooden spoon or wire whisk.
As mixture thickens, dilute with vinegar, when oil may be added more rapidly.
Finish and serve
Keep in cool place until ready to serve, then add remaining ingredients.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsifier that binds the oil and vinegar into a thick, stable sauce.
- Olive oil
- Provides the fat that, dispersed in the yolks, gives the sauce its body and richness.
- Vinegar
- Adds acidity that balances the richness and thins the sauce as it thickens.
- Mustard
- Helps stabilise the emulsion and adds sharpness.
The step that matters
Adding the oil. Oil must be added slowly at first, drop by drop, so the yolk can absorb it into a stable emulsion. Adding it too fast can break the sauce into separate oil and liquid.
Swap the parsley
How well each one fits the dish's main ingredients (mustard, sugar, egg, olive, vinegar, capers, shallot):
- Tarragonfits better
- Dillfits about as well
- Parsleythe original
- Thymefits about as well
Fit is the average pairing score against mustard, sugar, egg, olive, vinegar, capers, shallot. Candidates are from the same food group and used in at least 100 recipes.
