Korean Swimming Crab Soup (Kkotge-tang) is a spicy Korean seafood stew made with fresh blue crabs simmered in a rich, flavorful broth. The natural sweetness of the crab blends beautifully with the spicy seasoning, creating a deep and savory taste. When made with seasonal crabs, it becomes even sweeter and more aromatic—a perfect dish to warm up during the cold winter months.
