Raisins(葡萄干) in ice cream, in chocolate, and in cookies…Your favourite snacks cannot be without raisins!

But do you know how people get raisins from full and juicy grapes? Dry(晒干) them in the sun? Well, that may be one way. But people from Xinjiang have another way.

People there build many “blockhouses(碉堡)” near a grape garden.

People build many “blockhouses” on the hillside. The blockhouses are usually three metres tall and are as big as the size of a classroom.

They are quite different from the houses we live in. They have lots of holes in the wall. Inside there are many wooden shelves.

After picking the grapes, people put them on the shelves. Because of the hot weather, hot dry wind gets through the holes in the wall and dries the grapes up. 30 to 45 days later, the fruit will turn into soft, sweet raisins!

In around the year 535, people in Xinjiang started to send raisins as presents to the emperor(皇帝). This means that 1,500 years ago people began to know how to make raisins!
