Why it works: Mustard and tarragon 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Emulsify with the oil and form the body of the dressing.
- Salad oil
- Adds richness and a smooth, silky texture as it emulsifies.
- Thick béchamel sauce
- Thickens the dressing and gives it a creamy body.
- Cream
- Adds moisture and softens the flavour and texture.
- Tarragon vinegar
- Adds acidity and a sharp, aromatic note.
The step that matters
Gradually incorporate the salad oil. Adding oil slowly lets the egg yolk emulsify it into the mixture. Adding it too fast can break the emulsion, leaving the dressing oily and separated instead of smooth.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, mustard, sugar, sauce, tarragon, vinegar, cream):
- Capersfits better
- Nutmegfits better
- Dillfits better
- White pepperthe original
Fit is the average pairing score against egg, mustard, sugar, sauce, tarragon, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
