“Sushi means 'raw fish.'”

The idea that sushi exclusively means 'raw fish' is a widespread misunderstanding. Historically, the term "sushi" actually translates to "sour-tasting" or "vinegared rice," referring to the distinctive seasoned rice that is its foundation (Review). The dish originated in Southeast Asia as a method of preserving fish by fermenting it with rice and salt. In these early forms, the rice itself was often discarded after serving its purpose in preservation.

Over centuries, as this culinary practice spread to Japan, the preparation evolved. During the Muromachi period, people began consuming the fermented rice along with the fish. Later, in the Edo period, the introduction of rice vinegar dramatically shortened the fermentation process, making sushi a quicker, more accessible food. While raw fish, known as sashimi when served on its own, became a popular and iconic topping for many types of sushi, it is not a mandatory ingredient. Many sushi varieties feature cooked seafood, vegetables, or egg, all united by the presence of vinegared rice.

This common misconception likely stems from the visual prominence of raw fish in many popular sushi preparations, particularly as the dish gained global recognition. The striking appearance of expertly sliced raw fish often overshadows the crucial, yet less visually dramatic, vinegared rice. People frequently conflate sushi with sashimi, which is indeed just thinly sliced raw fish or seafood without rice. Understanding that sushi is defined by its specially prepared rice, rather than solely by raw fish, opens up a diverse world of flavors and ingredients within this celebrated Japanese cuisine.
