Horseradish appears in a variety of products in the supermarket and specialty food shops: Basic prepared horseradish is the grated fresh horseradish root mixed with distilled vinegar. Spices or other ingredients may be added (such as salt, sugar, cream or vegetable oil) to enhance and protect flavor.

To relish the full flavor of processed horseradish, it must be fresh and of high quality. Color varies from white to creamy beige. As processed horseradish ages, it browns and loses potency. Replace with a fresh jar for full flavor enjoyment.

Varieties of prepared horseradish include Cream Style Prepared Horseradish, Horseradish Sauce, Beet Horseradish and Dehydrated Horseradish. Distinguishing characteristics may be ingredients or texture -- fine or coarse ground. The true horseradish enthusiast has several favorites, depending on the end use.

Cocktail sauce with fresh horseradish is another winner, and has many uses beyond its usual role, as a flavorful accompaniment for seafood.

Mustard with fresh horseradish also adds a rich and spicy zing to cold cuts or hot entrees.
