Since it is high in fat content, it must be extremely fresh if served raw. The fatty, rich taste resembles that of saba (mackerel), but "dialed down", with a smooth, light flavor that even those who aren't fans of strong hikarimono fish will appreciate.
A grilled Sanma (Pacific Saury) is often served with the head and the tail. Firstly, please insert the chopsticks from head to tail and flake the flesh away from the bone. It's easier to flake in making a cut along the backbone with your chopsticks
