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 vinegar, giving the dressing a smooth, creamy body.
Olive oil
Provides fat that gives the dressing richness and a silky mouthfeel.
Mustard
Acts as an emulsifier that helps hold the oil and vinegar together and adds sharpness.
Vinegar
Adds acidity that brightens the dressing and balances the richness of the oil.
Egg white
Beaten and folded in, it adds air and lightness to the dressing.

The step that matters

Adding the oil slowly to the egg yolk. Oil must be added gradually so the yolk can disperse it into tiny droplets. Adding it too fast can cause the emulsion to break, leaving the dressing oily and separated.

Swap the mustard

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

  1. Capsicumfits better
  2. Cucumberfits about as well
  3. Tomatofits about as well
  4. Mustardthe original

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