Why it works: Olive and lemon are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 11,922 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Sauce Mayonnaise
Ingredients
Directions
Prepare
Chill the egg yolk and olive oil in the refrigerator before use.
Make the mayonnaise
In a bowl, combine the egg yolk, white pepper, and coarse sea salt, mixing gently.
Slowly add the olive oil drop by drop while stirring steadily in one direction.
Continue adding oil until about ½ cup is incorporated, adjusting with vinegar if the mixture starts to crack.
Finish and serve
For acidity, add lemon juice after the mayonnaise is made, if desired.
Serve very cold with salads.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Its lecithin emulsifies the oil and water so the sauce thickens instead of separating.
- Olive oil
- Forms the bulk of the sauce and, dispersed into droplets, gives it its rich, thick body.
- Vinegar
- Acidity helps stabilise the emulsion and can rescue a mixture that starts to break.
The step that matters
Adding the oil. Oil must be added slowly, drop by drop at first, while stirring in one direction. Fine droplets are dispersed and coated by the egg yolk's emulsifier; adding oil too fast overwhelms it, so the mixture splits and will not thicken.
