The main ingredient in sushi is vinegared rice, also known as "shari" or "sushi-meshi." Sushi consists primarily of this specially prepared rice, which is seasoned with a mixture of vinegar, sugar, and salt to achieve its distinctive flavor. Different types of sushi incorporate various toppings and fillings, including fresh fish, seafood, vegetables, and sometimes tropical fruits. While fish is commonly associated with sushi, the rice is what fundamentally defines sushi as a dish. Sushi can be enjoyed in various forms, such as nigiri, maki, and sashimi.
