Hamachi nigiri sushi is a traditional type of nigiri sushi. It consists of hand-pressed sushi rice that's topped with slices of young Japanese amberjack, also known as yellowtail tuna. The dish has a soft texture and flavors that are not as deep as salmon nigiri sushi or tuna nigiri sushi.
The fish is sometimes seared with a blowtorch until lightly charred. Traditionally, this type of sushi is eaten by hand in a single bite. It's usually accompanied by soy sauce, wasabi, or pickled ginger (
gari) on the side. The lower quality version of this dish is known as buri nigiri sushi, prepared with older and bigger yellowtail tuna.
