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
- Raw egg yolks
- Emulsify the olive oil into a thick, stable paste that gives the salad its body.
- Olive oil
- Adds richness and a smooth, creamy texture when emulsified with the yolks.
- Whitefish
- Provides the main flesh and savory flavor of the salad.
- Lemon juice
- Adds acidity that brightens the flavor and cuts the richness of the oil and yolks.
- Prepared mustard
- Contributes sharpness and helps stabilize the emulsion.
The step that matters
Adding the olive oil. Oil must be added slowly, drop by drop, so it disperses into the yolks. Adding it too fast breaks the emulsion, leaving a greasy, separated paste instead of a thick, smooth dressing.
Swap the mustard
How well each one fits the dish's main ingredients (whitefish, egg, olive, pepper, lemon):
- Capsicumfits better
- Spinachfits better
- Tomatofits about as well
- Mustardthe original
Fit is the average pairing score against whitefish, egg, olive, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
