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 ↓
Chicken Salad
Ingredients
Directions
Cook the chicken
Boil the chicken in water with a generous pinch of salt until tender, then let it cool in the water.
Remove all skin, bones, and gristle from the chicken, and cut the meat into pieces (do not chop).
Add a little salt and the white part of the celery to the chicken, and toss with a fork until light.
Set the chicken mixture aside in a cool place or on ice while you prepare the dressing.
Make the dressing
In a bowl, mix the egg yolks, dry mustard, sugar, cayenne pepper, and salt.
Gradually add the salad oil, about 1 tablespoon at a time, mixing well.
When you reach the last 2 tablespoons of oil, beat in the lemon juice until the dressing turns white and creamy.
Add the remaining oil and beat well until the dressing is thick enough to spread.
Optionally, mix in chopped capers, cucumber pickles, or olives.
Serve
Garnish the salad dish with lettuce leaves before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil into the dressing, thickening it into a spreadable, creamy mass.
- Salad oil
- Provides the fat that, emulsified with the yolks, gives the dressing its body and richness.
- Lemon juice
- Adds acidity that brightens the dressing and helps it turn pale and creamy.
- Chicken
- Forms the main body of the salad, providing protein and a tender texture.
- Celery
- Adds crisp texture and a fresh, vegetal crunch to the chicken.
The step that matters
Adding the oil gradually to the yolks. Egg yolks emulsify oil only when the oil is added slowly while beating. Adding it too fast lets the oil separate, so the dressing stays loose instead of thick and creamy.
Swap the capers
The recipe marks capers as optional. How well each one fits the dish's main ingredients (chicken, celery, egg, mustard, sugar, pepper, lemon):
- Tarragonfits better
- Dillfits better
- Parsleyfits better
- Capersthe original
Fit is the average pairing score against chicken, celery, egg, mustard, sugar, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
