육수 is a Korean broth made by simmering meat, bones, and vegetables. It serves as a flavorful base for various dishes, including soups and stews. Common ingredients include beef, chicken, or seafood, along with aromatics like garlic, onion, and ginger. The process of making 육수 typically involves boiling the ingredients for several hours to extract their flavors. This rich broth enhances the taste of dishes such as 김치찌개 (kimchi stew) and 떡국 (rice cake soup), making it an essential component of Korean cuisine.
