Why it works: Tarragon and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 602 recipes mention both. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Tartar Sauce
Ingredients
Directions
Break the yolks into a bowl and add the salt and mustard.
Stir in 1 tablespoon of olive oil, then alternate with 1 tablespoon of the mixed vinegars, stirring well until the sauce reaches the right consistency.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and vinegar to form a thick, smooth sauce.
- Olive oil
- Provides fat that gives the sauce its rich body and mouthfeel.
- Mustard
- Helps hold the oil and vinegar together as an emulsion and adds sharpness.
- Tarragon vinegar
- Adds acidity and a sharp, herbal aroma to balance the rich oil.
The step that matters
Adding the oil and vinegar. Oil must be added slowly while stirring, alternating with vinegar, so the yolks can emulsify it. Adding too much at once can break the sauce into a greasy, separated mixture.

Fit is the average pairing score against egg, mustard, olive, tarragon, vinegar, pepper. 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).
