Oritang is a variety of guk, Korean soup or stew made by slowly simmering duck and various vegetables. Ori means "duck" and tang is another name for guk in Korean. While its recipe depends on region and taste, the soup is generally in a form of a clear soup. Some variants can contain chili pepper powder to make the soup spicy like maeuntang (spicy fish soup) or roasted perilla seeds to thicken the dish.
