The primary ingredient of traditional sushi is vinegared rice, known as "shari" or "sushi-meshi." This specially prepared rice is seasoned with a mixture of vinegar, sugar, and salt, giving it a unique flavor and slightly sticky texture that allows it to hold its shape when rolled or molded. Sushi can be accompanied by various ingredients, such as fresh fish (sashimi), vegetables, and seaweed (nori), but without the vinegared rice, it would not qualify as sushi. The balance of flavors in sushi underscores the importance of this ingredient in crafting the dish.
