Why it works: Olive and capers match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 1,688 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw egg yolks
- Emulsify the oil and vinegar, giving the dressing a creamy, thick body.
- Olive oil
- Provides fat and richness, forming the body of the dressing as it is beaten in.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the oil and yolks.
- Hard-boiled eggs
- Add body and a mellow, rich texture from the cooked yolks.
The step that matters
Gradually add the olive oil while continuing to beat. Oil added too quickly can overwhelm the yolks and break the emulsion, so the dressing separates instead of turning thick and creamy.
Swap the capers
The recipe marks capers as optional. How well each one fits the dish's main ingredients (egg, olive, vinegar, pepper, sugar):
- Tarragonfits better
- Dillfits better
- Parsleyfits about as well
- Capersthe original
Fit is the average pairing score against egg, olive, vinegar, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
