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 and olive oil in the refrigerator before use.
In a bowl, separate the egg yolk from the white and discard the white.
Add white pepper and salt to the yolk and mix gently.
Make the mayonnaise
Slowly add the olive oil drop by drop while stirring steadily in one direction.
Continue adding oil until about ½ cup is incorporated.
If the mixture starts to separate, add a few drops of vinegar and mix until smooth.
Optionally, add lemon juice for acidity after the mayonnaise is made.
Serve
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, holding the sauce together as a thick emulsion.
- Olive oil
- Forms the bulk of the emulsion, giving the mayonnaise its richness and body.
- Vinegar
- Adds acidity that helps stabilise the emulsion when it begins to split and sharpens flavour.
The step that matters
Adding the oil slowly. Oil must be dispersed into tiny droplets while the yolk is still fluid enough to surround them. Adding it too fast overwhelms the yolk's emulsifier, so the mixture separates into oil and liquid instead of becoming thick and smooth.
