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 mayonnaise
Combine egg yolks, mustard, salt, and pepper in a bowl.
Stir quickly with a wooden spoon.
Gradually add oil, starting with a few drops and then more quickly, while adding a few drops of vinegar at intervals.
Continue stirring until mixture thickens to consistency of very thick cream.
In hot weather, place the bowl in a vessel of crushed ice while making the mayonnaise.
Finish the sauce
Stir in the cream.
If sauce is too thick, add a little cold water.

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 and water, giving the sauce its thick, smooth body.
- Salad oil
- Provides the fat that, dispersed into droplets, thickens the sauce into mayonnaise.
- Tarragon vinegar
- Adds acidity that brightens flavor and helps stabilize the emulsion.
- French mustard
- Acts as an extra emulsifier that helps hold the oil and yolk together.
The step that matters
Adding the oil gradually. Oil must be added slowly at first so droplets disperse fully in the yolk; adding it too fast can break the emulsion so the sauce turns oily and runny.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper, tarragon, vinegar, cream):

- Asparagusfits about as well
Fit is the average pairing score against egg, pepper, tarragon, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
