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

- 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.
