Horseradish is a root vegetable that is native to southeastern Europe but is widely cultivated in many parts of the world, including the Netherlands. It has a strong, pungent flavor and is often used as a condiment or seasoning in dishes like roast beef, smoked fish, and sauces. In the Netherlands, horseradish is sometimes grated and mixed with cream or sour cream to make a traditional condiment called “pepper sauce”. Horseradish is also a good source of vitamin C, fiber, and other nutrients.
