Why it works: Lemon and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,137 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Mayonnaise Sauce
Ingredients
Directions
Make the emulsion
Break the yolk of a fresh egg into a bowl and add salt and pepper.
Beat the mixture until thick.
Gradually add olive oil, two or three drops at a time, until about ½ cup has been used and the mixture is thick and yellow.
Once 8 teaspoons of oil have been added, stir in 1 teaspoon of white vinegar.
Continue adding oil and vinegar in these proportions until all the oil is used.
Finish the sauce
For a creamier texture, add a few drops of lemon juice and tarragon vinegar for flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Lecithin in the yolk emulsifies the oil and water, holding the sauce together and thick.
- Olive oil
- Supplies the fat that, dispersed in droplets, gives the sauce its thick, rich body.
- White vinegar
- Adds acidity that brightens flavor and helps stabilize the emulsion.
The step that matters
Adding the oil gradually. Oil must be added a few drops at a time while beating, so each droplet is coated by yolk before more is added. Adding it too fast breaks the emulsion, leaving the sauce thin and oily.
Swap the tarragon
The recipe marks tarragon as optional. How well each one fits the dish's main ingredients (egg, pepper, olive, vinegar, lemon):
- Parsleyfits about as well
- Tarragonthe original
- Dillfits about as well
- Thymefits less well
Fit is the average pairing score against egg, pepper, olive, vinegar, lemon. Candidates are from the same food group and used in at least 100 recipes.
