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 yolk
Emulsifies the oil and water, holding the dressing together as a smooth, stable mixture.
Salad oil
Provides fat that gives the dressing its rich body and mouthfeel.
Mixed mustard
Helps stabilize the emulsion and adds a sharp, tangy flavour.
Lemon juice or vinegar
Adds acidity that brightens the flavour and thins the dressing to a creamy consistency.

The step that matters

Adding the oil gradually. Egg yolk can only emulsify a limited amount of oil at a time. Adding oil slowly lets the droplets disperse and bind, forming a thick paste. Pouring it in too fast can make the mixture break and separate.

Swap the mustard

How well each one fits the dish's main ingredients (egg, pepper, lemon):

  1. Spinachfits better
  2. Capsicumfits better
  3. Asparagusfits better
  4. Mustardthe original

Fit is the average pairing score against egg, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
