What is Frigate tuna?
Sōda-gatsuo are frigate tunas ( Auxis thazard ). In Japanese cuisine, these fish are processed into sōdabushi , a product much like katsuobushi , though not really used in fine-dining restaurants or as condiment, but as a fish stock ingredient at more budget type popular-dining places, e.g., soba shops. This word is also written as "宗太鰹". Although fresh sōda-gatsuo might be eaten as sashimi or grilled, it has a lot of dark-red meat ( chiai ), so it is valued much less than the similar katsuo (skipjack tuna). It also degrades quickly so shipment to market is limited. The frigate tuna hirasōda is considered to be superior to sōda-gatsuo .
