Why it works: Olive and vinegar are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 12,297 recipes. Both carry isoamyl acetate, which smells banana, fruity. The science ↓
Mayonnaise Sauce
Ingredients
Directions
Make the emulsion
Separate the yolks from the whites of the eggs and remove the germ.
In a bowl, stir the yolks with a wooden spoon.
Slowly add the olive oil drop by drop while stirring continuously in one direction.
Season and finish
Add a little salt and pepper, then a few drops of vinegar or lemon juice.
Ensure the sauce is thick enough for a spoon to stand upright in it.
Make in a cool place and keep on ice during summer.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Their lecithin emulsifies the oil and water, holding the sauce together as a thick emulsion.
- Olive oil
- Forms the body of the sauce as droplets suspended in the yolk, giving richness and thickness.
- Vinegar or lemon juice
- Adds acidity that brightens the flavour and helps balance the richness of the oil.
The step that matters
Adding the oil slowly. Oil must be added drop by drop while whisking constantly. If it goes in too fast, the droplets cannot be dispersed by the yolk's emulsifier and the mayonnaise breaks into a separated, oily mixture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
