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 ↓
French Chicken Salad
Ingredients
Directions
Prepare the chicken
Remove the skin and fat from the boiled fowl and cut the flesh into small shreds, no longer than ½ inch.
Mix the shredded chicken with the chopped celery.
Make the dressing
Prepare the dressing by mashing the yolks of the hard-boiled eggs with a wooden spoon until smooth.
Add salt, mustard, cayenne, vinegar, and salad oil to the egg yolks to taste, mixing until smooth.
Assemble and garnish
Lay the shredded chicken in the center of a flat dish and cover it thickly with the dressing, mixing thoroughly.
Garnish the top with finely chopped white lettuce and minced egg whites.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boiled fowl
- Provides the main body of the salad as lean, shredded protein.
- Hard-boiled eggs
- Yolks are mashed into a smooth, rich dressing that binds the salad.
- Celery
- Adds a crisp texture that contrasts with the soft chicken and dressing.
- Salad oil
- Adds fat and richness, helping the mashed yolk dressing become smooth and creamy.
- Vinegar
- Adds acidity that brightens the rich yolk dressing.
The step that matters
Mashing the yolks into the dressing. Yolks must be mashed fully smooth before the oil and vinegar are added. Lumps stay visible and the dressing can separate or turn grainy instead of forming a creamy emulsion.
Swap the celery
How well each one fits the dish's main ingredients (egg, mustard, pepper, vinegar, lettuce):
- Tarragonfits better
- Capersfits better
- Dillfits better
- Celerythe original
Fit is the average pairing score against egg, mustard, pepper, vinegar, lettuce. Candidates are from the same food group and used in at least 100 recipes.
