International Horseradish Festival, Collinsville IL
Horseradish is a root plant from the mustard family. The root is harvested in the spring and fall and is sold to processors who grate the root releasing the oils that distinguish horseradish from all other flavors. The oil creates a hot and spicy flavor. The ground horseradish is mixed with distilled vinegar to stabilize the "heat." This basic formula may also contain other spices or ingredients, such as sugar, salt, cream or vegetable oil. Additional ingredients vary by processors. Generally speaking ground horseradish and vinegar are the primary components in the basic prepared horseradish on the market. In the United States, an estimated 24 million pounds of horseradish roots are ground annually to produce 6 million gallons of prepared horseradish. Collinsville, Illinois and the surrounding area provides the perfect climate for growing horseradish. Cold winters provide dormancy for the root and the long warm summers are excellent for growing. The soil is rich in potash, which is a vital nutrient in the growth of the horseradish.
