Horseradish has a pungent, spicy flavor similar to onion but stronger. Unlike the spice of hot peppers, which is sensed on the tongue, the spice of horseradish is felt mainly in the nose and throat. Although vinegar is applied to this raw root to help stabilize the heated spice, the spicy essence remains.
