Kkori gomtang is a traditional oxtail soup originating from South Korea. The soup is usually made with a combination of oxtails, garlic, peppercorns, scallions, salt, and black pepper. The oxtails are soaked in cold water, drained, and boiled in water for about three hours while skimming the foam off the top of the surface.
They're removed from the pot, while the garlic, salt, and peppercorns are added to the pot and simmered for half an hour before they're discarded. The oxtails are placed in soup bowls and the broth is ladled over them. The milky white soup is garnished with chopped scallions, seasoned with black pepper, and enjoyed while still warm.
