Saba – Mackeral – (59 calories per sushi slice) Two varieties of Saba, the ‘Honsaba’ and the ‘Gomasaba’ are caught in the Sea of Japan. Fall is the best time to eat Saba because the meat acquires more fat. Saba is probably most well-known for ‘Saba-zushi’ which is filleted slices of Saba marinated in vinegar and sugar and rolled with sushi rice. Saba-zushi is served at family gatherings during the Fall Harvest festivals, particularly in the Kansai area. Saba contains vitamin B2 ans DHA.
