Sushi (すし, 寿司, 鮨?) is a type of food preparation originating in Japan, consisting of cooked vinegared rice (鮨飯 sushi-meshi) combined with other ingredients (ネタ neta) such as seafood, meat, vegetables and sometimes tropical fruits. Ingredients and forms of sushi presentation vary widely, but the ingredient which all sushi have in common is rice (also referred to as shari (しゃり) or sumeshi (酢飯)). Although commonly mistaken for sushi, sashimi, which is also a Japanese delicacy, consists of thinly sliced raw meat or fish and may or may not be served with rice.
Sushi can be prepared with either brown or white rice. It is often prepared with raw seafood, but some common varieties of sushi use cooked ingredients and many are vegetarian. Sushi is often served with pickled ginger, wasabi, and soy sauce. Popular garnishes are often made using daikon.
