Eat Brussels Sprouts Day is celebrated worldwide every January 31 to honor the often-overlooked Brussels sprout, a small vegetable that resembles miniature cabbages. This unofficial holiday encourages people to incorporate Brussels sprouts into their diets more frequently. The Brussels sprout is a cultivar of Brassica oleracea, first cultivated in Northern Europe around the 13th century, with the first written mention dating back to 1587. On this day, people are encouraged to enjoy Brussels sprouts, which can be prepared in various ways, including roasting, steaming, and sautéing. Roasting is particularly recommended as it enhances their sweetness while reducing bitterness. When cooked properly, Brussels sprouts develop a complex flavor that can vary based on the cooking method, making them a versatile addition to meals.
