Why it works: Pepper and tarragon 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 ↓
Mayonnaise Sauce
Ingredients
Directions
Prepare
Separate the yolks of the eggs into one bowl and the whites into another bowl.
Stir the yolks gently to break them.
Add the salt, pepper, and French vinegar to the yolks.
Make the mayonnaise
With your thumb partially covering the top of the salad oil bottle, pour the oil in drop by drop while whisking continuously until combined.
If desired, stir in the mustard or tarragon vinegar smoothly.

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 vinegar together as a thick, stable sauce.
- Salad oil
- Provides the fat that gives mayonnaise its rich, creamy body.
- French vinegar
- Adds acidity that brightens flavour and helps balance the richness of the oil.
The step that matters
Adding the oil drop by drop while whisking. Oil added too quickly cannot be absorbed by the yolk emulsifiers, so the mixture may split and fail to thicken. Slow, continuous whisking lets small oil droplets disperse evenly and form a stable emulsion.
Swap the tarragon
How well each one fits the dish's main ingredients (egg, pepper, vinegar):
- Tarragonthe original
- Dillfits about as well
- Parsleyfits less well
- Allspicefits less well
Fit is the average pairing score against egg, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
