Why it works: Tarragon and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,399 recipes. Both carry estragole, which smells anise, licorice. The science ↓

Egg and vinegar barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsifiers that hold the oil and water-based parts together, giving mayonnaise its thick, smooth body.
- Salad oil
- Forms the bulk of the emulsion, providing richness and a creamy texture when dispersed into the yolks.
- Tarragon vinegar
- Adds acidity and bright flavor that balances the richness of the oil and yolks.
The step that matters
Gradually add the salad oil while stirring. Adding oil too fast overwhelms the yolks' ability to emulsify, so the mixture can break and separate into oily liquid. Adding it slowly in a thin stream while stirring lets tiny oil droplets get coated and suspended evenly, producing a stable, thick emulsion.
Swap the tarragon
How well each one fits the dish's main ingredients (egg, vinegar, pepper):
- Tarragonthe original
- Dillfits about as well
- Parsleyfits less well
- Allspicefits less well
Fit is the average pairing score against egg, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
