Availability and Selection

In many supermarkets, fresh horseradish is available year-round. At farmers’ markets, however, it is sold only from early spring through late fall. Roots dug in the fall after the first frost are generally regarded as the most flavorful. Fresh horseradish roots should feel firm, look husky yet well formed, and be 6 to 8 inches/15 to 20 centimeters long. The skin should be light brown and blemish free. If the root is freshly dug, especially if purchased at a farmers’ market, it will have lots of dirt clinging to it and appear slightly darker. The flesh will be creamy white.
