Horseradish refers both to the root and the condiment made from grating it. The root has a notoriously pungent aroma and flavour, and when making prepared horseradish, this flavour often is mellowed by acidic ingredients such as vinegar. Prepared horseradish adds kick to sandwiches, cocktail sauce and vegetables. When making your own prepared horseradish, you can substitute the ingredients in it to create your own condiment.
Grate the horseradish in a food processor. Substitute an equal amount of black radish or wasabi root for the fresh horseradish root in the food processor.
Add 1 tbsp of lemon juice or vinegar to the horseradish to keep it from discolouring.
Toss the horseradish with salt to taste.
Add more lemon juice or white vinegar if the horseradish tastes too pungent for raw use, but leave it hot if you will cook the prepared horseradish because it mellows when cooked.
