Jook or juk (rice porridge) is a korean dish meant to conserve rice and to soothe sick, young, or elderly bellies. It's still enjoyed as a snack, breakfast, a light meal, or as comfort food for the sick. Pat jook is smooth and mild with a subtle sweetness, but can also be eaten without sugar in place of regular white rice. Juk accounts for a substantial portion of korean food. Even in ancient literature, about 40 kinds of rice porridge are described. There is a wide variety of porridge, such as huinjuk (made with only rice and water) and gokmuljuk (grain porridge made with red beans, barley, and rice), tarakjuk (rice porridge mixed with milk), yeolmaejuk (rice porridge mixed with pine nuts, walnuts, and jujubes), and gogijuk (rice porridge with beef or chicken added). These days, juk no longer serves as survival food in emergencies; it is now more highly prized as gourmet or energizing food with the addition of expensive ingredients such as ginseng and abalone. In luxurious korean restaurants, it is included as one of the courses in a full-course set menu, just like the soup course in western restaurants. Also, juk is very popular today as diet food. People in the southern areas like guangdong province mainly cultivate rice, so they eat rice porridge for breakfast more often than people in the north, who mainly cultivate wheat. There is quite a wide variety of different rice porridges according to the ingredients, which are either mixed in or added as a garnish, but the two main categories are huinjuk, and jaejuk (rice boiled with meat or fish).
