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
Prepare
Chop the herbs, capers, and anchovies very small.
In a bowl, combine the chopped ingredients with the egg yolk.
Make the sauce
Slowly add oil, stirring gently as you would for mayonnaise.
Add vinegar to taste, pouring it in gently to avoid breaking the sauce.
Stir in enough mustard to make the sauce fairly hot.

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 and binds the sauce into a smooth, thick texture.
- Oil
- Forms the body of the sauce, giving richness and a creamy texture.
- Vinegar
- Adds acidity that sharpens the flavour and balances the rich oil.
- Mustard
- Adds heat and sharpness, and helps stabilise the emulsion.
- Capers
- Contribute briny, acidic flavour that cuts through the richness.
- Anchovies
- Add savoury depth and umami to the sauce.
The step that matters
Adding the oil. Oil must be added slowly while stirring gently, so the egg yolk can emulsify it into the sauce. Adding it too fast or stirring too hard can cause the sauce to split and separate.
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.
