Why it works: Tarragon and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 824 recipes mention both. Both carry estragole, which smells anise, licorice. The science ↓
Tartare Sauce
Ingredients
Directions
Make the emulsion
In a bowl, beat the egg yolk well.
Gradually add the salad oil drop by drop while stirring continuously.
Once thickened, mix in the tarragon vinegar until the sauce is as thick as cream.
Finish the sauce
Add the chopped tarragon, chervil, anchovy sauce, and mustard, mixing well.
If the sauce curdles, add another egg yolk and mix until smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Acts as the emulsifier that holds the oil and vinegar together as a thick sauce.
- Salad oil
- Provides the fat that gives the sauce its rich body and creamy texture.
- Tarragon vinegar
- Adds acidity that sharpens the flavour and helps thicken the sauce to a creamy consistency.
- Mustard
- Contains natural emulsifiers that help stabilise the sauce and add sharp flavour.
The step that matters
Adding the oil drop by drop. Oil must be added slowly while whisking so the egg yolk lecithin can surround the droplets. Adding it too fast overwhelms the yolk, and the emulsion breaks and the sauce curdles.

Fit is the average pairing score against egg, tarragon, chervil, anchovy, sauce, vinegar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
