Why it works: Lemon and pepper 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
Emulsify the oil into the dressing, giving it a thick, creamy body.
Olive oil
Supplies fat that, emulsified with the yolks, gives richness and smooth texture.
Lemon juice
Adds acidity that brightens the flavour and balances the richness of the oil.
Egg whites
Folded in before cooking, they add structure and help thicken the mixture as it heats.
Flour
Thickens the dressing as it cooks, stabilising its body.

The step that matters

Cook slowly without boiling. Egg proteins set as they heat and can curdle or scramble if overheated. Cooking gently while stirring lets the mixture thicken smoothly without turning grainy.
