Sable fish, also known as black cod, is a deep-sea fish found in the North Pacific Ocean. It is prized for its rich, buttery flavor and high oil content, making it a popular choice in gourmet cuisine. Sable fish typically has a dark, silvery skin and can grow up to 3 feet long. This fish is often used in dishes like miso-glazed sable fish, where its natural richness complements the sweet and savory flavors of miso. Sable fish is also known for its health benefits, as it is a good source of omega-3 fatty acids, which are beneficial for heart health.
