Horse Mackerel (Aji)

アジ

Aji is commonly known as Japanese horse mackerel. It’s a small fish with a devoted following at sushi restaurants. Despite its name and appearance, aji is not a mackerel. It’s a type of jack and is related to hamachi and kanpachi.  The season for aji is from spring to fall, and they’re said to taste best in the summer. That said, you can find decent horse mackerel year-round.
