Goma saba is raw Hakata mackerel with sesame paste, soy and ginger. Served as an appetiser at most Hakata izakaya; an autumn-to-winter classic in fine-dining counters across Akasaka and Yakuin.
Where to eat it: 3 restaurants across 1 city.
Goma saba came from Hakata's Genkai Sea fishing tradition, where bonito-grade mackerel is rare-tossed with sesame paste, soy, mirin and ginger. The dish was first written about in late-19th-century records but only spread nationally with the Hakata izakaya boom of the 1980s. It is a winter and shoulder-season dish; the mackerel must be the freshest possible. Toriden, Kawataro and the Yatai stalls all run a version. The dish exports nervously: mackerel oxidises fast and goma saba does not travel well outside Kyushu.
Common allergens: Fish, Soy, Sesame
Tip from the editors. Sashimi-grade mackerel from a Japanese counter is essential. Supermarket mackerel will not work; oxidation is the enemy.
