Black cod miso is a popular Japanese dish made from black cod, a rich and buttery fish, marinated in a sweet and savory miso paste. The marinade typically includes ingredients like sake, mirin, and sugar, which enhance the fish's natural flavors. After marinating, the fish is usually grilled or broiled, resulting in a tender and flavorful dish. This dish is often served in high-end restaurants and is known for its melt-in-your-mouth texture. Black cod miso is not only delicious but also nutritious, as black cod is high in omega-3 fatty acids, making it a healthy choice for seafood lovers.
