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

What each ingredient does

Eggs
Eggs thicken as they cook, giving the dressing its body and setting it into a creamy texture.
Vinegar
Adds acidity that sharpens the flavour and balances the sweetness and richness.
Sugar
Adds sweetness that balances the acidity of the vinegar and mustard.
Butter
Adds fat that makes the dressing richer and smoother on the palate.
Mixed mustard
Adds sharpness and aroma that give the dressing its savoury bite.

The step that matters

Cook the mixture over steam, stirring constantly. Egg proteins set gradually as they heat. If the heat is too high or stirring stops, the eggs can scramble and the dressing becomes lumpy instead of smooth and thick.

Swap the mustard

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

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

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