Horseradish

Horseradish is a knobby, cream-colored root from the mustard family. When freshly grated, it delivers nasal-clearing heat and a sharp, mustardy aroma; use it raw to enliven sauces, dressings, and spreads, or fold it into creamy condiments because cooking softens its bite. It is sold as whole roots and as prepared or creamed horseradish in jars.

Originating in Eastern Europe, horseradish spread through Central Europe and the British Isles and became a staple in North American kitchens. Growers harvest in fall and early spring in temperate regions and hold roots in cold storage to supply markets year-round.
