Sablefish is highly prized for an intensely rich, buttery flavour – hence the nickname “butterfish” – and for its surprisingly delicate texture. Although commonly called “black cod,” this deep-sea fish, which can live up to 5,000 feet (1,500 metres) below the sea, is not part of the cod family.

Sablefish have a dark grayish-green body with a pale grey or white belly. Its sleek body is covered with small scales that feel vaguely furry to the touch. Sablefish inhabit shelf and deep-sea waters from central Baja California to Japan and the Bering Sea. Their high fat content provides a rich flavor and velvety texture.
