Miso-marinated black cod is a popular dish in Japanese cuisine, known for its rich flavor and buttery texture. The black cod, also known as sablefish, is marinated in a mixture of miso paste, sake, and sugar, which enhances its natural taste and adds a sweet and savory profile. After marinating, the fish is typically grilled or broiled, resulting in a caramelized exterior while remaining moist inside. This cooking method not only elevates the flavor but also highlights the fish's delicate qualities, making it a favorite among seafood lovers and a staple in many Japanese restaurants.
