Sushi originated in China, and it has been recorded in the ceremony of extending happiness in heian period code completed in 927 AD. It was invented by China people and spread to Japan from the coastal areas of China around the 3rd century BC.
The original sushi was only salted fish, but later it was salted fish with rice, and the fish was eaten with rice after being made. This is the predecessor of today's sushi cuisine. Although sushi first came from China, it has become one of the representatives of Japanese culture after thousands of years of development.
development history
the earliest sushi was a small food made of raw rice, fish and sauce, which can be eaten in one bite. Now there are many kinds of sushi, which can hold a lot of things, but it must be eaten in one bite. Japanese Sushi Sushi was recorded in the heian period Code "Yanxi Style" completed in 927 AD.
Sushi at that time was a way to preserve fish. Rub salt on the fish, press it with heavy objects and let it ferment naturally. When it is sour, it can be eaten, and its taste is very good. It is said that this way was spread from China to Japan. This method is time-consuming and laborious, and soon developed into a way of simply soaking fish in vinegar.
Sushi refers to any food in which other fillings are added to the vinegar-mixed rice. Nowadays, Japanese sushi, in addition to the grip (that is, sushi that we often eat now), also includes rolled sushi and box sushi.
