Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. 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-based liquids together in a smooth sauce.
- Olive oil
- Supplies the fat that, dispersed into the yolks, forms the body and richness of the sauce.
- French vinegar
- Adds acidity that sharpens the flavour and helps the sauce thicken as it is mixed.
- Lemon juice
- Adds bright acidity and thins the sauce to a smooth, creamy consistency.
The step that matters
Adding the olive oil gradually while mixing. Oil added too fast cannot be absorbed by the egg yolk emulsifier, so the sauce breaks and separates into oily layers. Adding it slowly in a thin stream lets each droplet be surrounded and suspended before more is added.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
