Required : One stick of horseradish.
Half a teaspoonful of made mustard. One teaspoonful of castor sugar. One tablespoonful of vinegar. Quarter of a pint of cream. A pinch of salt.
Lay the horseradish in cold water for a short time ; it will then be easier to scrape. Wash, scrub, and peel the stick, then grate it as finely as possible. Add to it the mustard, sugar, salt, and vinegar, and mix all together. Whip the cream slightly, and add it. Mix all well together, and keep it on ice or in a cold place until it is required.
N.B. - If a cheaper variety is preferred, use milk in place of cream, and add a few fine breadcrumbs, otherwise the sauce will be too thin.
