Nigiri sushi is a type of Japanese dish made with sushi rice and fresh fish. The sushi rice is hand formed into a small clump, and the fish is sliced and pressed on top of it. In some cases, nigiri sushi uses a small strip of toasted seaweed called nori to bind the whole mixture together, although this is not obligatory.
Nigiri - slices of fish on vinegared rice with wasabi. The word sushi is often ambiguous for non-native Japanese. We think of it as being interchangeable with raw fish. Sushi is vinegared rice topped with other ingredients. Sashimi, which is slices of raw fish alone, is not sushi because it isn't accompanied with rice. Originally, sushi was fermented fish with rice preserved in salt, and this was a staple dish in Japan for a thousand years until the Edo Period (1603 to 1868) when contemporary sushi was developed.
