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

What each ingredient does

Mustard
Gives the sauce its sharp, pungent flavour and helps hold the mixture together.
Egg
Thickens the sauce as it heats and gives it a smooth, rich body.
Vinegar
Adds acidity that sharpens the flavour and balances the sweetness.
Sugar
Softens the sharpness of the mustard and vinegar for a rounder taste.

The step that matters

Cooking over low heat with constant stirring. Egg proteins thicken the sauce as they warm, but if the mixture gets too hot or is left unstirred, the egg can scramble and turn grainy. Gentle heat and constant stirring keep it smooth.

Swap the mustard

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

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

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