Why it works: Vinegar and white pepper are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 1,154 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Mayonnaise Sauce
Ingredients
Directions
Prepare
Strain the yolks of four eggs into a basin and place in a cool place or on ice.
Add 1 teaspoon of salt.
Make the mayonnaise
Pour in salad oil drop by drop while stirring continuously.
When 1 teaspoon of oil is blended, add 1 tablespoon of vinegar.
Continue adding oil and vinegar alternately until the mixture is thick like cream.
Season
Add white pepper to taste and more salt if necessary.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.
-
Vinegar + white peppertop 20% of all pairsSmell alikelowCooked together1,154 recipes
Shared aroma: isobutyraldehyde (malty, green).
-
Egg + white peppertop 21% of all pairsSmell alikelowCooked together2,312 recipes
Shared aroma: 2-methylbutyraldehyde (malty, chocolate).
-
Egg + vinegartop 33% of all pairsSmell alikelowCooked together12,922 recipes
Shared aroma: acetic acid (sour, vinegar).
Egg and vinegar barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsifier that holds the oil and vinegar together as a thick, stable sauce.
- Salad oil
- Supplies the fat that, dispersed in droplets, gives mayonnaise its rich, thick body.
- Vinegar
- Adds acidity for sharp flavour and helps keep the emulsion stable.
The step that matters
Adding the oil drop by drop at the start. Oil added too fast at first cannot be absorbed by the yolks, so the emulsion breaks and the mixture separates into a greasy liquid. Slow addition lets fine droplets form and be coated by lecithin in the yolk, building a thick, stable sauce.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, vinegar):
- Tarragonfits better
- Dillfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
