Cabbage is a leafy green or purple vegetable with tightly packed layers of leaves forming a round or elongated head. It has a mild, slightly sweet flavor and a crunchy texture when raw, but it becomes tender and sweeter when cooked. Cabbage is commonly used in a variety of dishes, including salads, slaws, soups, stews, stir-fries, and fermented foods like sauerkraut and kimchi. It is rich in vitamins, particularly vitamin C and vitamin K, as well as dietary fiber and antioxidants.
