Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Adds richness and a smooth, creamy body that mellows the sharp horseradish.
- Made mustard
- Adds sharpness and a pungent flavour that complements the horseradish.
- Vinegar
- Adds acidity that brightens the sauce and balances its richness.
- Grated horse-radish
- Provides the main pungent heat and characteristic flavour of the sauce.
The step that matters
Heat the mixture gently, but do not boil. Boiling can cause the cream to curdle or separate, and it can drive off the volatile compounds that give horseradish its pungency.
Swap the radish
How well each one fits the dish's main ingredients (mustard, pepper, sugar, vinegar, cream, horse):
- Radishthe original
- Horseradishfits about as well
- Capsicumfits less well
- Broccolifits less well
Fit is the average pairing score against mustard, pepper, sugar, vinegar, cream, horse. Candidates are from the same food group and used in at least 100 recipes.
