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 cream and thicken the sauce as they gently heat.
- Rich, sweet cream
- Adds moisture and richness, giving the sauce a smooth, creamy body.
- Lemon or lime juice
- Adds acidity that brightens the flavour and balances the richness.
- Dry mustard
- Helps stabilise the emulsion so the sauce stays smooth and does not separate.
- Sugar
- Adds a little sweetness that rounds out the acidity.
The step that matters
Cook until the mixture thickens. Egg yolks thicken from gentle heat but scramble if they get too hot. Keep the double boiler at a low heat and stir constantly so the sauce thickens smoothly.
Swap the mustard
How well each one fits the dish's main ingredients (lemon, egg, sugar, pepper, cream):
- Spinachfits better
- Capsicumfits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against lemon, egg, sugar, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
