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 ↓
Salad Dressing
Ingredients
Directions
In a bowl, combine the egg yolks, oil, red pepper, salt, and mustard.
Add the lemon juice and mix well.
If making chicken salad, substitute chicken fat for the oil.
Finally, gently fold in the thick cream just before serving.

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 thick, smooth body.
- Oil
- Provides fat that, emulsified with the yolks, gives the dressing its richness and body.
- Lemon juice
- Adds acidity that brightens the flavour and balances the richness of the oil and cream.
- Thick cream
- Adds richness and a softer, lighter texture when folded in just before serving.
The step that matters
Fold in the cream just before serving. Cream is added last and gently so it stays light and airy. Beating or stirring it in early can overwork it and make the dressing heavy or thin, and it can separate if left to sit.
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.
