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 ↓
Mayonnaise Dressing
Ingredients
Directions
Prepare
Chill utensils and ingredients thoroughly.
Make the emulsion
In a bowl, beat the egg yolks until creamy.
Add salt, sugar, dry lemon juice, and vinegar; beat again.
Slowly add olive oil while beating until thickened.
If the mixture gets too thick, add 1 tablespoon of lemon juice or vinegar.
Continue adding oil and alternating with lemon juice or vinegar until fully incorporated.
Finish
For improved flavor, fold in whipped cream just before serving.
Optionally, add whipped egg whites to increase bulk.

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 water so the sauce stays thick instead of separating.
- Olive oil
- Supplies the fat that, dispersed into droplets, forms the body and richness of the sauce.
- Vinegar
- Adds acidity for sharp flavor and helps stabilise the emulsion.
- Lemon juice
- Adds acidity for brightness and can thin the sauce when it gets too thick.
- Whipped cream
- Adds airy volume and a softer, richer texture when folded in at the end.
The step that matters
Slowly add olive oil while beating. Oil must be added a little at a time so it breaks into tiny droplets that the egg yolk lecithin can hold. Adding it too fast makes the mayonnaise split and become oily and runny.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (egg, sugar, olive, vinegar, cream):
- Vanillafits better
- Strawberryfits about as well
- Raspberryfits about as well
- Lemonthe original
Fit is the average pairing score against egg, sugar, olive, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
