Aji, known as Japanese horse mackerel, is a sought-after fish in sushi cuisine, appreciated for its bold, slightly oily flavor and firm texture. Sushi chefs often showcase Aji in its freshest form, serving it as sashimi or sushi to highlight its distinctive taste and satisfying mouthfeel.
In its sashimi form, it is usually accompanied by grated ginger, which complements its rich taste and enhances its natural qualities.
