Sushi (すし, 寿司, 鮨, 鮓, 寿斗, 寿し, 壽司?) is a Japanese food consisting of cooked vinegared rice sushi-meshi (鮨飯, “sushi rice”) combined with other ingredients (neta [寿司ネタ]), usually raw fish or other seafood. Neta and forms of sushi presentation vary widely, but the ingredient which all sushi have in common is vinegared rice. The rice is also referred to as (shari [しゃり]) and “sumeshi” (酢飯, “vinegared rice”).
Raw meat (usually but not necessarily seafood) sliced and served by itself is sashimi. Many non-Japanese use the terms sashimi and sushi interchangeably, but the two dishes are actually distinct and separate. Sushi refers to any dish made with vinegared rice.
I have several videos on Youtube if you would like to see how to make it – it’s easier than you think!
