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 Sance
Ingredients
Directions
Work the yolks of the raw eggs into a smooth paste.
Add salt, cayenne, mustard, and olive oil; mix thoroughly.
Gradually add the strained juice of half a lemon and then the olive oil, one teaspoon at a time.
Every fifth teaspoon, add a few drops of lemon juice until you have used two lemons and the half cup of oil.
If too thick, gradually add the cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Lecithin in the yolks emulsifies the oil and lemon juice, giving the sauce its thick, smooth body.
- Olive oil
- Forms the fat phase of the emulsion, providing richness and a thick, glossy texture.
- Lemon juice
- Adds acidity that brightens the sauce and helps keep the emulsion stable.
The step that matters
Adding the oil slowly. Oil must be added in small amounts while whisking so droplets disperse fully. Adding it too fast breaks the emulsion, and the sauce separates into a greasy, runny mixture.
Swap the lemon
How well each one fits the dish's main ingredients (egg, pepper, mustard, olive, tarragon, vinegar, cream):
- Lemonthe original
- Limefits about as well
- Avocadofits about as well
- Cherryfits less well
Fit is the average pairing score against egg, pepper, mustard, olive, tarragon, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
