Raisins（葡萄干） in ice cream，in chocolate bars，and in cookies…Our favorite snacks can not be without raisins!
Have you ever thought about how people get raisins from full and juicy grapes？Dry them in the sun？well，that's one way．But people from Xinjiang have another way．They make the best raisins in China．
People there build many"blockhouses（碉堡）"out of earth near a grapegarden．It's in these blockhouses that the best raisins are made．
Many"blockhouses"are builton the hillside．They're usually three meters 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 pout them on the shelves．Because of the hot weather，hot dry windgets through the holes in the wall and dries the grapes up．Thirty to forty-five days later，the fruits will turn into soft，sweet raisins．
In around the year 535，people in Xinjiang started to send raisins as gifts to the emperor．This means that about 1，500 years ago people there already knew hot to make raisins．
