Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolk
Its lecithin emulsifies the oil and vinegar, holding the sauce together as a thick, stable mixture.
Olive oil
Forms the fat phase of the emulsion, giving mayonnaise its rich body and smooth texture.
Vinegar
Adds acidity that sharpens flavor and helps keep the emulsion stable.
Ground mustard
Its natural emulsifiers help stabilize the emulsion and add a sharp, savory note.

The step that matters

Gradually add the olive oil while beating briskly. Oil must be dispersed into tiny droplets in the egg yolk. Adding it too fast overwhelms the yolk's emulsifiers, so the mixture fails to thicken and separates.

Swap the mustard

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

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

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