Sautéed Alaskan Black Cod with Endive and Hazelnuts

Black cod, despite its name, is not a true cod. Its other names—sablefish and butterfish—suit it better: its texture is as silky as sable, its flavor as rich as butter. I love the Japanese pairing of black cod and miso, but in this recipe, black cod gets a French treatment, a smothering with hazelnut brown butter. Ask your fishmonger where the black cod is from. It’s overfished in California and Oregon so look for black cod from Alaska, where the commercial fishing is better regulated. Black cod has a single row of bones that is very difficult to remove when the fish is raw. You can ask your fishmonger to remove the bones or cut them out yourself before cooking. Or just cook the fish bones and all; it’s easy to spot them and eat around them.
