Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a smooth, creamy body to the sauce.
- Cream
- Adds moisture and a smooth, thick texture to the sauce.
- Grated horse-radish
- Provides the sharp, pungent heat that defines the sauce.
- Distilled white vinegar
- Adds acidity that sharpens the flavour and balances the richness.
The step that matters
Ensure the sauce is as thick as good cream. Thickness depends on the fat and cream being fully worked together, and the sauce is loosened by added liquid. Adding vinegar too early can thin it, so check consistency before adjusting seasoning.
Swap the radish
How well each one fits the dish's main ingredients (horse, mustard, sugar, vinegar, olive, pepper, butter):
- Radishthe original
- Capsicumfits about as well
- Broccolifits less well
- Cucumberfits less well
Fit is the average pairing score against horse, mustard, sugar, vinegar, olive, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
