  3. Slowly add the oil (or melted butter) and vinegar while stirring constantly until thick and light.

  4. Chill the dressing on ice until ready to use.

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

What each ingredient does

Egg yolks
Emulsify the oil and vinegar and thicken the dressing into a creamy texture.
Oil
Adds fat and richness, carrying flavor and giving the dressing body.
Vinegar
Adds acidity that brightens the dressing and balances the richness of the oil.
English mustard
Helps stabilize the emulsion and adds sharp, pungent flavor.

The step that matters

Adding the oil and vinegar slowly while stirring constantly. Egg yolks can only hold oil in suspension if it is added gradually while whisking. Adding it too fast causes the emulsion to break, leaving a thin, separated dressing instead of a thick, light one.

Swap the mustard

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

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

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