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 Vinaigrette
Ingredients
Directions
Make the dressing
In a bowl, combine 4 tablespoons of oil with ¼ teaspoon of coarse sea salt.
Mix in ½ tablespoon of French vinegar gradually.
Add ¼ teaspoon of mignonette pepper or ordinary pepper, mixing well.
Dress the salad
Toss the salad lightly to coat the leaves evenly before adding vinegar.
Sprinkle 1 teaspoon of tarragon over the salad and toss again before serving.
Garnish and serve
For garnish, add hard-boiled eggs, or a mixture of tarragon, chervil, and small spring onion if desired.
Finish with nasturtium flowers and leaves just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oil
- Forms the base of the dressing and carries the flavour of the other ingredients.
- French vinegar
- Adds acidity that sharpens the dressing and balances the oil.
- Tarragon
- Adds a fresh, slightly anise-like aroma to the dressing and salad.
The step that matters
Mix in the vinegar gradually. Adding the vinegar slowly while mixing lets the oil and vinegar form a temporary emulsion, with tiny droplets of each dispersed through the other. Pouring it in all at once makes the dressing separate quickly and taste sharp in places and greasy in others.
Swap the tarragon
The recipe marks tarragon as optional. How well each one fits the dish's main ingredients (vinegar, pepper, egg, chervil, onion, mustard):
- Tarragonthe original
- Capersfits about as well
- Dillfits less well
- Parsleyfits less well
Fit is the average pairing score against vinegar, pepper, egg, chervil, onion, mustard. Candidates are from the same food group and used in at least 100 recipes.
