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

What each ingredient does

Eggs
Thicken as they cook, giving the dressing a custard-like body.
Butter
Adds richness and a smooth, creamy mouthfeel to the dressing.
Vinegar
Provides the sharp acidity that balances the sweetness and richness.
Mustard
Adds sharp flavour and helps emulsify the fat into the mixture.
Sugar
Softens the sharpness of the vinegar, balancing the acidity.

The step that matters

Thickening the eggs over the kettle. Egg proteins set gently with steady, moderate heat. If the mixture gets too hot or is stirred too little, the eggs can scramble or curdle instead of thickening smoothly.

Swap the mustard

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

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

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