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

What each ingredient does

Sugar
Adds sweetness to balance the sharpness of the vinegar.
Vinegar
Provides the acidity that gives the dressing its tang.
Mustard
Adds sharp flavor and helps emulsify the dressing.
Onion
Contributes sharp aroma and flavor to the dressing.

The step that matters

Refrigerate until very cold. Chilling lets the flavors of the onion, mustard, and seasonings blend and mellow into the vinegar and water. Serving it warm would taste harsher and less balanced.

Swap the onion

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

  1. Horseradishfits better
  2. Capsicumfits better
  3. Radishfits better
  4. Onionthe original

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