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

What each ingredient does

Mustard
Provides the main sharp flavor and pungency of the condiment.
Brown sugar
Adds sweetness that balances the sharpness of the mustard and vinegar.
Hot vinegar
Adds acidity and liquid that loosens the mixture and sharpens the heat of the mustard.

The step that matters

Letting the mixture sit. Resting allows the flavors to blend and mellow, so the mustard tastes less harsh. Tasting it straight away may give a sharper, unbalanced result.

Swap the mustard

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

  1. Capsicumfits better
  2. Mustardthe original
  3. Cabbagefits less well
  4. Cucumberfits less well

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