Why it works: Mustard and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Chicken Salad
Ingredients
Directions
Prepare the chicken
Boil the chickens in salted water until tender, then let them cool.
Remove the dark meat and cut the chicken into small pieces.
Add salt if needed, then mix in sweet cream and a little extract of celery.
Make the dressing
In a bowl, combine the egg yolks, mustard, sugar, cayenne pepper, and salt.
Slowly add the Lucca oil while stirring continuously until thickened.
Add vinegar to taste just before finishing the dressing.
Serve
Mix some dressing with the chicken and broken lettuce.
Serve the chicken on a dish and pour the remaining dressing over it.
Garnish with slices of hard-boiled eggs, olives, and pickled beets.

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 and vinegar into a thick, stable dressing.
- Lucca oil
- Provides fat and richness, forming the body of the dressing as it emulsifies.
- Sweet cream
- Adds moisture and richness to the chicken, softening the texture.
- Mustard
- Helps stabilize the emulsion and adds a sharp, tangy flavor.
- Chickens
- Provide the main protein and bulk of the salad.
The step that matters
Slowly add the Lucca oil while stirring continuously. Adding oil too fast to the egg yolks can break the emulsion, leaving the dressing greasy and thin instead of thick and smooth. Gradual addition lets the yolk lecithin surround the oil droplets so they stay suspended.
Swap the lettuce
How well each one fits the dish's main ingredients (chicken, cream, egg, mustard, pepper, vinegar, olive):
- Capsicumfits better
- Spinachfits about as well
- Lettucethe original
- Horseradishfits about as well
Fit is the average pairing score against chicken, cream, egg, mustard, pepper, vinegar, olive. Candidates are from the same food group and used in at least 100 recipes.
