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

What each ingredient does

Horse-radish
Provides the sharp, pungent heat that defines the sauce.
Cream
Adds richness and a smooth, creamy texture that softens the sharpness.
Vinegar
Adds acidity that brightens the flavour and cuts the richness of the cream.
Mixed mustard
Adds extra sharpness and savoury depth.
Sugar
Balances the heat and acidity so the sauce tastes rounded.

The step that matters

Heat gently without boiling. Cream mixed with acid like vinegar can curdle and separate when overheated. Gentle, indirect heat in a water bath keeps the sauce smooth and emulsified.

Swap the radish

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

  1. Radishthe original
  2. Horseradishfits about as well
  3. Capsicumfits less well
  4. Broccolifits less well

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