Aji nigiri sushi

Aji nigiri is a traditional type of nigiri sushi. It consists of hand-pressed sushi rice that's topped with slices of aji or horse mackerel fish. Aji or horse mackerel is smaller than other mackerel and its flavor is lighter. This fish pairs well with pickled ginger (gari), spring onions (negi), and mirin. It's usually marinated in vinegar in order to remove excess fat and the texture becomes smoother. Before serving, this nigiri sushi is often topped with negi, and it's typically enjoyed in a single bite (or two).
