food from all over the world: sushi

This week, I want to introduce one of my favorite meals-sushi! Before, it was a method to preserve food: decrease pH value by adding acetic acid(醋酸), which prevented microorganism from flourishing to slow down the speed the food became spoiled at.

origin

Between the late Western Han dynasty and the early Eastern Han dynasty, sushi was first transported from Southeast Asia to the south of China, and it was not until the three kingdoms period that sushi was spread all over China. After it was transported to Japan, it became universal in the Mid-Edo era. Later, the rice just cooked was matched by acetic acid, which fastened the fermentation and speeded up the entire manufacturing process. Because of continuous innovation and invention, sushi was developed as a delicate and diverse dish.

Many people think of sushi as rice wrapped up with seaweeds. In fact, sushi is a general term, and it can be divided into three kinds in Japan.

1.nigiri zushi(握壽司):

It is the most typical. After mixing rice, sugar and acetic acid, put fish on it.

2.maki zushi(捲壽司)

It was from Japanese casinos. The gamblers wanted to save time but they still needed to eat. Therefore, they rolled up rice and tuna(鮪魚), which can fill their stomach and don't adhere to their hands.

3.hako zushi(箱壽司)

It is a representative meal in Kansai. Put the acid rice and other materials in layers into the wood case, and press it by a board. After taking it out and cut it into pieces, you can enjoy the delicious hako zushi.
