Brussels sprouts are small, round cruciferous vegetables that belong to the Brassicaceae family, which includes cabbage, broccoli, and kale. These miniature cabbage-like vegetables grow in clusters along the stem of the Brussels sprout plant. They are typically 1 to 1.5 inches in diameter and have tightly packed leaves that range in color from light green to deep green. Brussels sprouts have a mild, slightly bitter flavor with nutty undertones. When cooked properly, they become tender and develop a delightful caramelized sweetness. Brussels sprouts are rich in vitamins C and K, fiber, and antioxidants, making them a nutritious addition to a balanced diet.
