Gomtang (Slow-Simmered Ox Bone Beef Soup)

The prolonged cooking extracts collagen, marrow, and fat from the bones, giving the liquid a creamy texture and a deep beefy flavor that needs only salt and black pepper to taste complete. Before the long simmer begins, the bones should be soaked in cold water for at least an hour to draw out the blood, then parboiled briefly in a fresh pot of water and rinsed clean so that the final broth comes out clear and free of off flavors. The brisket is removed partway through cooking, sliced thin against the grain, and arranged on top of the steaming soup for serving. Sliced green onion and a generous shake of black pepper cut cleanly through the richness of the milky broth. The most common way to eat gomtang is with a bowl of steamed rice submerged directly into the soup, letting the grains soak up all the flavor. This is slow food in the truest sense - the hours of effort yield a pot that can sustain a family across two meals - and it remains one of the dishes Koreans reach for instinctively when the cold sets in.
