Also known as butterfish or black cod (though it’s not related to codfish), this large cold-water fish lives in the north Pacific Ocean. Its flaky white flesh is flavorful and, yes, buttery, with an omega-3 oil content that rivals that of salmon. Sablefish tastes milder than other fatty fish, but, like them, it can be prepared by high-heat cooking methods such as grilling. Limited supplies and high demand in Japan have driven up the price of sablefish, but it’s a healthful and flavorful splurge. (And it’s an environmentally sound choice.)
