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
- Emulsify with the butter and thicken the sauce as they gently cook.
- Melted butter
- Provides fat that gives the sauce its rich texture and smooth body.
- Lemon juice
- Adds acidity that brightens the richness of the butter and yolks.
The step that matters
Whisk over low heat without boiling. Egg yolks begin to set around 65 to 70°C and scramble if overheated, so the sauce can curdle. Gentle indirect heat from the hot water bath lets the yolks thicken smoothly into a stable emulsion.
