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 ↓
Mayonnaise Sauce
Ingredients
Directions
Make the emulsion
In a small round-bottomed bowl, combine the egg yolks, salt, cayenne pepper, and mustard, and mix well with a wooden spoon or whisk.
Add half the oil drop by drop while stirring briskly.
Finish and rest
Gradually stir in the tarragon and chili vinegar.
Add the remaining oil drop by drop, then stir in the white vinegar.
Let the sauce stand for 30 minutes before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks bind the oil and vinegar into a stable, creamy emulsion.
- Salad oil
- Supplies the fat that forms the body and richness of the sauce.
- Mustard
- Its natural emulsifiers help hold the oil and vinegar together.
- Tarragon vinegar
- Adds acidity and the distinctive aromatic flavour of tarragon.
- White vinegar
- Adds sharp acidity that brightens and balances the richness of the oil.
- Chili vinegar
- Adds acidity and a warm, pungent flavour to the sauce.
The step that matters
Adding the oil drop by drop. Egg yolks can only disperse so much oil at once. Adding it slowly while stirring lets each droplet be coated and suspended. Adding too fast overwhelms the yolks, and the sauce breaks and separates.
Swap the mustard
How well each one fits the dish's main ingredients (egg, tarragon, vinegar, pepper):
- Mustardthe original
- Shallotfits about as well
- Capsicumfits about as well
- Cucumberfits less well
Fit is the average pairing score against egg, tarragon, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
