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 ↓
Mayonnaise Sauce
Ingredients
Directions
Place the yolks of the eggs in a bowl.
Add a pinch of salt and a little pepper.
Stir well with a wooden spoon, adding the oil drop by drop until thick.
Once thick as butter, mix in the tarragon vinegar, mustard, and chopped chives.
Ensure the sauce is thick before serving.

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 into the sauce, giving it a thick, creamy structure.
- Salad oil
- Provides the fat that, dispersed in the yolks, thickens the sauce into mayonnaise.
- Tarragon vinegar
- Adds acidity that brightens the rich sauce and balances its fat.
- Mustard
- Helps stabilise the emulsion so the sauce holds together.
The step that matters
Adding the oil drop by drop. Oil added too quickly cannot be absorbed by the yolks and the emulsion breaks, leaving a runny, separated sauce. Slow addition lets the yolk lecithin surround tiny oil droplets, building thickness gradually.
Swap the chive
How well each one fits the dish's main ingredients (egg, tarragon, vinegar, mustard, pepper):
- Shallotfits better
- Horseradishfits better
- Lettucefits better
- Chivethe original
Fit is the average pairing score against egg, tarragon, vinegar, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
