Lore & Background
Horseradish has been cultivated since antiquity, mentioned by Dioscorides, Pliny the Elder, and Cato. The early Renaissance herbalists Pietro Andrea Mattioli and John Gerard depicted it under Raphanus. Its modern Linnaean genus Armoracia was first applied by Heinrich Bernhard Ruppius in 1745, though Linnaeus called it Cochlearia armoracia. Both roots and leaves were used in traditional medicine during the Middle Ages, and the root was used as a condiment on meats in Germany, Scandinavia, and Britain. It was introduced to North America during European colonization, with George Washington and Thomas Jefferson mentioning it in garden accounts. European settlers used it to stimulate glands, stave off scurvy, and as a diaphoretic for the common cold.
Reader's Guide
Horseradish is significant for its distinctive pungent taste, derived from allyl isothiocyanate, which is released when the root is cut or grated. This compound serves as a natural defense against herbivores. The plant is perennial in hardiness zones 2–9 and can become invasive if not managed. In the United States, the most concentrated growth occurs in the Collinsville, Illinois region, while Europe produces 30,000 metric tonnes annually, with Hungary as the largest producer at 12,000 tonnes. Culinary uses include prepared horseradish mixed with vinegar, horseradish sauce in Europe (often served with roast beef in the UK), and as a component of Bloody Mary cocktails and cocktail sauce in the US. It is also used in Christian Easter traditions as a reminder of Jesus' suffering, and on Passover, many Ashkenazi Jews use grated horseradish as Maror.
Did You Know?
- Intact horseradish root has little aroma; pungency develops only when cut or grated.
- The compound allyl isothiocyanate degrades over days at 37 °C (99 °F), causing horseradish sauces to lose pungency.
- Horseradish is likely native to Southeastern Europe and Western Asia.
- The word 'horseradish' is attested in English from the 1590s, combining 'horse' (meaning strong or coarse) and 'radish'.
