Why it works: Tarragon and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 901 recipes. Both carry methyleugenol, which smells clove, spice. The science ↓

Directions
Pound the anchovies and tarragon very fine in a mortar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Provide a salty, savory depth that defines the sauce's character.
- Hard-boiled egg yolks
- Emulsify with the oil and mustard to give the sauce a thick, smooth body.
- Mustard
- Adds sharpness and helps stabilize the emulsion.
- Oil
- Forms the fat base of the emulsion, giving richness and smoothness.
The step that matters
Gradually mix in the mustard and oil. Adding the oil slowly, a little at a time, lets the egg yolk emulsify it into a stable sauce. Adding it too fast can cause it to break and separate.
Swap the mustard
How well each one fits the dish's main ingredients (tarragon, egg, sauce):
- Shallotfits better
- Mustardthe original
- Chivefits about as well
- Asparagusfits about as well
Fit is the average pairing score against tarragon, egg, sauce. Candidates are from the same food group and used in at least 100 recipes.
