“Sushi means raw fish”

The idea that sushi exclusively means raw fish is a widespread misunderstanding, but the truth lies in its historical roots and linguistic origin. The word "sushi" actually translates to "sour-tasting" or "vinegared rice," referring to the distinct flavor of the rice that is a cornerstone of the dish. Historically, sushi began in Southeast Asia as a method of preserving fish in fermented rice. The rice was not originally meant to be eaten but served as a fermenting agent to keep the fish fresh, and it was typically discarded before the fish was consumed.

As this preservation technique made its way to Japan, it evolved significantly. During the Edo period, vinegar began to be incorporated into the rice, which sped up the fermentation process and made the rice palatable to eat alongside the fish. This innovation transformed sushi from a simple preservation method into a culinary art form where the seasoned rice became the central, defining ingredient. Many traditional sushi varieties, such as those with cooked eel, shrimp, or various vegetables, demonstrate that raw fish is not a prerequisite for sushi.

The common belief that sushi means raw fish likely stems from the prominence of raw fish in many popular sushi preparations, particularly in Western countries. Furthermore, there's a frequent confusion between sushi and sashimi. Sashimi is indeed thinly sliced raw fish or seafood served without rice, and its name literally means "pierced body" or "sliced meat." While sashimi is often served in sushi restaurants, it is a distinct dish, and understanding this difference helps clarify that the defining element of sushi is its specially prepared vinegared rice.
