Sushi is a Japanese dish consisting of seasoned rice, typically combined with seafood, vegetables, and other ingredients, often served with soy sauce, wasabi, and pickled ginger. The term "sushi" actually refers to the rice, which is prepared with vinegar, salt, and sugar. While often associated with raw fish, sushi can include cooked fish, vegetables, or even fruits, and can be presented in various forms like rolls, pressed blocks, or hand-formed pieces.
