Introduction to Marlin and Sashimi
Marlin, belonging to the family Istiophoridae, is found in tropical and subtropical waters around the globe. There are several species of marlin, with the blue marlin, black marlin, and striped marlin being among the most recognized. These fish are highly prized for their meat, which is often cooked in various ways to bring out its rich, savory flavor. On the other hand, sashimi is a delicacy in Japanese cuisine, consisting of thinly sliced raw fish served without cookery. The key to enjoying sashimi lies in the freshness and quality of the fish, which must be free of parasites and have a distinct flavor and firm texture.
Characteristics of Marlin
Marlin is characterized by its firm, meaty flesh, which is often considered ideal for grilled or broiled dishes.
