The Origin and History of Sushi
The origin of sushi can be traced back to Southeast Asia around the 4th century BC, where it began not as the cuisine we know today, but as a method of preserving fish. This early form, known as "narezushi," involved fermenting fish with salt and rice. The rice, used primarily to facilitate the fermentation process, was discarded afterward, and only the preserved fish was consumed. This preservation technique made its way to Japan via China, forming the foundation of early Japanese sushi.
By the Edo period (17th-19th centuries), sushi had evolved into a form much closer to its modern incarnation. "Edomae-zushi" emerged in Edo (present-day Tokyo), where chefs began seasoning rice with vinegar and pairing it with fresh seafood, giving rise to the early form of "nigiri-zushi." During this time, sushi transitioned from a preserved food into a fresh, ready-to-eat delicacy emphasizing taste and quality, gradually spreading from high-end cuisine to become a popular food for the masses.
