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 cream, giving the dressing a smooth, thick body.
Mustard
Helps hold the oil and vinegar together and adds a sharp flavour.
Olive oil
Provides fat for richness and a smooth mouthfeel.
Cream
Adds moisture and body, mellowing the sharpness of the vinegar.
Vinegar
Adds acidity that balances the sweetness and richness.

The step that matters

Adding the oil and vinegar gradually. Adding oil or vinegar too quickly can break the emulsion, so the dressing separates instead of turning smooth and creamy. Slow addition while stirring lets the egg yolk and mustard bind the liquids into a stable mixture.

Swap the mustard

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

  1. Capsicumfits about as well
  2. Mustardthe original
  3. Cucumberfits about as well
  4. Asparagusfits less well

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