Why it works: Mustard and capers 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Mashed yolks emulsify with oil to form a smooth, thick dressing.
- Oil
- Adds fat and richness, and is emulsified into the yolks for a smooth texture.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil.
- Mustard
- Helps stabilise the emulsion and adds a sharp, tangy flavour.
- Cooked chicken
- Provides the main protein and bulk of the salad.
- Celery
- Adds crisp texture and a fresh, mildly savoury crunch.
The step that matters
Gradually add oil to the yolk mixture until smooth. Adding oil slowly lets the lecithin in the egg yolks coat the droplets and form a stable emulsion. Adding it too fast can cause the dressing to break and separate.
Swap the celery
How well each one fits the dish's main ingredients (chicken, egg, mustard, pepper, vinegar, capers):
- Tarragonfits better
- Dillfits better
- Parsleyfits better
- Celerythe original
Fit is the average pairing score against chicken, egg, mustard, pepper, vinegar, capers. Candidates are from the same food group and used in at least 100 recipes.
