Why it works: Lemon and olive 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
Make the emulsion
In a bowl, combine the egg yolks and salt, and beat thoroughly.
Slowly add the olive oil, a few drops at a time, while beating constantly until all the oil is incorporated.
Add the vinegar and lemon juice in the same manner.
Finish
Finally, fold in the whipped cream.

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 liquids together as a smooth, thick mixture.
- Olive oil
- Fat that gives the dressing its richness and body.
- Vinegar
- Adds acidity that brightens flavour and balances the richness of the oil.
- Lemon juice
- Adds acidity and fresh citrus flavour that lifts the dressing.
- Whipped cream
- Adds air and a light, fluffy texture to the dressing.
The step that matters
Add the oil slowly while beating constantly. The yolk lecithin must coat tiny oil droplets as they form. Adding oil too fast overwhelms the yolk, so the emulsion breaks and the mixture separates into a greasy liquid.
Swap the lemon
How well each one fits the dish's main ingredients (vinegar, egg, olive, cream):

Fit is the average pairing score against vinegar, egg, olive, cream. Candidates are from the same food group and used in at least 100 recipes.
