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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Act as the emulsifier, holding the oil and water in the sauce together and giving body.
- Olive oil
- Provides the fat that makes the dressing thick and rich while carrying its flavor.
- Lemon juice
- Adds acidity that brightens the flavor and balances the richness of the oil.
- Heavy cream
- Whipped and folded in, it adds lightness and a softer, creamier texture.
The step that matters
Adding the olive oil gradually. Egg yolks emulsify oil only when it is added slowly while beating. Pouring it in too fast overwhelms the yolks, so the oil separates and the dressing fails to thicken.
