Brett Lynch, corporate executive chef for the Alaska Seafood Marketing Institute, prepares Alaska Black Cod in Acacia Honey Marinade. The combination of sweet honey, salty and umami-rich soy sauce, and tart vinegar in this marinade brings out the luxuriously rich and buttery texture of the black cod. The internal temperature of the fish should reach about 140°F when done. In place of pea leaves, you can also pair the black cod with wilted spinach and seared shitake mushrooms. Black cod is also called sablefish and butterfish, and Alaska is home to the world’s largest wild black cod fishery. The fish are sustainably harvested from late February to mid November, but also available frozen year-round.
