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

What each ingredient does

Mustard flour
Forms the thick body of the sauce and carries the sharp mustard flavour.
Horseradish
Adds pungent heat that sharpens the sauce's flavour.
Vinegar
Adds acidity that balances the heat and sweetness of the sauce.
Cream
Adds fat that softens the sharpness and gives a smoother texture.

The step that matters

Combining the horseradish mixture with the mustard mixture. Mustard flavour develops and sharpens after its volatile compounds form when ground mustard meets liquid, and heat or acid change its intensity. Adding the hot horseradish mixture too early or too quickly can make the sauce harsh or change its texture, so combine gradually until the consistency is right.

Swap the horseradish

  2. Shallotfits about as well
  3. Radishfits less well
  4. Beetrootfits less well

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