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
Yolk lecithin acts as an emulsifier, holding the oil and lemon juice together as a stable sauce.
Olive oil
Supplies the fat that, dispersed in droplets, thickens the sauce into a rich, creamy texture.
Lemon juice
Adds acidity that brightens flavour and helps the emulsion set into a stable, thick consistency.

The step that matters

Adding the oil and lemon juice slowly. Oil must be dispersed into tiny droplets while beating so the egg can emulsify it. Adding too much at once breaks the emulsion, leaving the sauce thin and oily.
