Why it works: Chervil and tarragon 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 ↓
Tartar Sauce
Ingredients
Directions
Make the emulsion
Place the egg yolk in a bowl and beat it for 1-2 minutes with salt, pepper, and dry mustard.
Gradually add the salad oil, first in drops and then in teaspoonfuls, beating well after each addition.
After every six teaspoonfuls of oil, add a teaspoon of vinegar.
Finish and serve
Add the minced shallots, gherkins, chervil, tarragon, and cayenne to the sauce.
Mix thoroughly and serve.
If not used immediately, keep in a cool place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil and water in the vinegar, giving the sauce its thick, creamy body.
- Salad oil
- Forms the bulk of the sauce, giving it richness and a smooth texture when emulsified.
- Vinegar
- Adds acidity that brightens the rich oil and balances the flavour.
- Shallots
- Contribute a mild, sharp onion flavour and aroma throughout the sauce.
- Gherkins
- Add sourness, crunch and a tangy bite to the sauce.
The step that matters
Adding the oil gradually. Egg yolk can only hold a limited amount of oil before the emulsion breaks. Adding oil in drops at first, and beating well after each addition, lets the lecithin in the yolk coat the droplets so the sauce stays thick and smooth instead of separating.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper, vinegar, shallot, chervil, tarragon):
- Chivefits better
- Lettucefits about as well
- Mustardthe original
- Beetrootfits about as well
Fit is the average pairing score against egg, pepper, vinegar, shallot, chervil, tarragon. Candidates are from the same food group and used in at least 100 recipes.
