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 the oil and lemon juice, giving the dressing a smooth, thick body.
- Oil
- Provides fat that carries flavour and gives the dressing its rich texture.
- Lemon juice
- Adds acidity that brightens the dressing and balances the richness of the oil and yolks.
- Thick cream
- Adds richness and a softer, lighter texture when folded in at the end.
The step that matters
Fold in the cream gently just before serving. Cream is whipped-soft fat that deflates and thins if overmixed or left to sit. Folding it in gently keeps it airy and prevents the dressing from becoming loose or greasy.
Swap the mustard
How well each one fits the dish's main ingredients (egg, pepper, lemon, cream):
- Spinachfits better
- Asparagusfits better
- Capsicumfits better
- Mustardthe original
Fit is the average pairing score against egg, pepper, lemon, cream. Candidates are from the same food group and used in at least 100 recipes.
