Overview of ice cream Ice cream, which is now a popular food, was a delicacy that only princes, ministers and nobles could afford more than 700 years ago. It is said that the popularity of ice cream began in 1904. That year, at the World's Fair in St. Louis, the first American-made ready-to-serve ice cream machine appeared. Some people say that Americans began to eat ice cream at the end of the 19th century. It is said that when Washington took office as President of the United States in 1789, he paid a large sum of money to hire a black man who was skilled in making ice cream to make ice cream for him at the banquet. The ice cream made by this black man was highly praised by Washington. So the black man was worth a hundred times as much. Later, he set up his own shop to make ice cream and sell it, which was very popular. But later, some people believed that ice cream existed in Britain earlier than in the United States. It was in the early 17th century. It is said that King Charles I of England held a grand banquet at the palace and sent people to invite "ice cream experts" from France to make ice cream. So, it seems that France had ice cream earlier than the UK. It is said that in 1550 AD, the name "ice cream" first appeared on the recipe of a Paris cafe. The problem came again. This coffee shop was opened by an Italian lady. Therefore, many people believe that ice cream first came from Italy. At that time, ice cream was made of frozen milk, eggs, etc. In fact, we were the first to have ice cream in China. That was 2000 years ago. "The Book of Songs·Bin Feng" says: "The second one is called: Chisel the ice to rush, the third one is called Ling Yin." "Ling Yin" is the room for storing ice. During the Zhou Dynasty, people had used ice to offer sacrifices and serve guests. Therefore, the "Li" of Zhou said: "Ling people hold ice to offer sacrifices to guests." Our ancestors did not eat ice in winter, but stored the ice in winter until summer. It is edible, so there are "ice rooms" and "lingren" who are responsible for storing ice. This is made more clear in "Zuo Zhuan": "The ancients said that ice is hidden in the Northern Continent, and it comes out in the Western Continent. It is hidden in deep mountains and poor valleys, dry and cold. It is also used. , a funeral ceremony for the guests." Marco Polo, the famous Italian traveler in ancient times, traveled to China. In his travel notes, there is a record of seeing Chinese milk ice in the 13th century. It can be seen that at that time, people were using milk to make ice cream. The reason why Italians have ice cream is probably inspired by what Marco Polo recorded.
