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 ↓

Directions
In a wooden bowl, combine the yolks of the hard-boiled eggs and the raw eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw eggs
- Emulsify the oil and lemon juice into a thick, creamy dressing.
- Hard-boiled egg yolks
- Add richness and help bind the dressing smoothly.
- Olive oil
- Provides fat that gives the dressing body and a smooth texture.
- Lemon juice
- Adds acidity that brightens the dressing and balances the richness of the oil.
The step that matters
Adding the olive oil. Oil must be added slowly while mixing constantly so the egg proteins can hold it in tiny droplets. Adding it too fast can cause the dressing to separate or break.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (egg, pepper, olive, lemon):
- Capsicumfits better
- Spinachfits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against egg, pepper, olive, lemon. Candidates are from the same food group and used in at least 100 recipes.
