Why it works: Tarragon and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 824 recipes. Both carry estragole, which smells anise, licorice. The science ↓
French Salad
Ingredients
Directions
Make the sauce
In a bowl, mash the yolks of the hard-boiled eggs with a wooden spoon.
Moisten the yolks with the raw egg.
Add the salt, black pepper, and cayenne to the egg mixture.
Gradually mix in the oil and vinegar until you have a smooth sauce.
Stir in the shredded onion, chervil, and tarragon if using plain vinegar.
For a richer sauce, add thick cream or melted butter.
Finish
Chop the egg whites and add them to the salad if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Their crumbled richness forms the base of the salad and thickens the sauce body.
- Raw egg
- Emulsifies the oil and vinegar, helping the mashed yolks bind into a smooth sauce.
- Oil
- Supplies fat that, emulsified with the egg, gives the sauce its smooth, creamy texture.
- Vinegar
- Adds acidity that brightens the rich yolk and oil mixture.
The step that matters
Gradually mix in the oil and vinegar. Adding oil slowly lets the raw egg emulsify it into the yolks. Pouring too fast can split the mixture into a greasy, separated sauce instead of a smooth one.
Swap the tarragon
The recipe marks tarragon as optional. How well each one fits the dish's main ingredients (egg, pepper, olive, onion, chervil, cream):
- Tarragonthe original
- Capersfits about as well
- Parsleyfits less well
- Garlicfits less well
Fit is the average pairing score against egg, pepper, olive, onion, chervil, cream. Candidates are from the same food group and used in at least 100 recipes.
