Horseradish Sauce

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the sauce

  1. In a bowl, combine grated horseradish, salt, sugar, pepper, mustard, vinegar, and cream.

  2. Transfer the mixture to a jar.

Cook gently

  1. Place the jar in a saucepan of boiling water.

  2. Cook slowly for 5 minutes, ensuring the mixture does not boil to prevent curdling.

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

What each ingredient does

Grated horseradish
Provides the sharp, pungent heat that defines the sauce.
Cream
Adds richness and body, softening the horseradish's sharpness.
Vinegar
Adds acidity that brightens the flavour and balances the cream.
Mixed mustard
Adds sharpness and depth that complements the horseradish.

The step that matters

Cook slowly without boiling. Gentle heat in the water bath warms the cream and thickens the sauce gradually. If the mixture boils, the cream can curdle, leaving the sauce grainy and separated.
