Why it works: Capers and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 624 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Ravigote Sauce
Ingredients
Directions
Chop the herbs, capers, and anchovies very small.
In a bowl, combine the chopped ingredients with the egg yolk.
Slowly add the oil while whisking, similar to making mayonnaise.
Gently pour in vinegar to taste, ensuring the sauce doesn't curdle.
Stir in enough mustard to make the sauce pleasantly spicy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil into the sauce, giving it a thick, creamy body.
- Oil
- Forms the bulk of the emulsion, providing richness and a smooth texture.
- Vinegar
- Adds acidity that brightens the sauce and balances the richness of the oil.
- Mustard
- Adds sharpness and spice, and helps stabilise the emulsion.
- Anchovies
- Contribute a savoury, salty depth that rounds out the herbs and capers.
The step that matters
Slowly add the oil while whisking. Adding oil too fast before the yolk has emulsified can break the sauce, leaving it oily and separated. Adding it in a thin, steady stream lets the lecithin in the yolk surround the oil droplets, creating a stable, thick emulsion.
Swap the capers
How well each one fits the dish's main ingredients (egg, vinegar, mustard):
- Tarragonfits about as well
- Capersthe original
- Dillfits less well
- Allspicefits less well
Fit is the average pairing score against egg, vinegar, mustard. Candidates are from the same food group and used in at least 100 recipes.
