The background about ice cream is:

1. As far as the West is concerned, it is said that around the 4th century BC, Alexander the Great preserved the winter snow in the Alps during his expedition to Egypt. Fruits or juices were frozen and consumed, thus boosting the morale of soldiers. There are also records showing Palestinians using ice and snow in caves or canyons to beat the heat. Among the various theories, the most convincing one started in China. In 1292, Marco Polo's "Oriental Insights" written after traveling in China recorded that he brought the recipe for frozen milk, his favorite in Metropolis, back to Venice and spread it in northern Italy. The traditional frozen food from the East was introduced to the West through Marco Polo, and was further developed and industrialized, thus giving birth to today's ice cream.

2. Frozen Milk, which has been consumed in China a long time ago, was introduced to the West by Marco Polo. However, it is as popular all over the world as it is today. It was first opened in Paris around 1660. Cafe Procope', Italian Cotelli makes fruit juices that add flavor to oranges or lemons, freezes them and sells them as ice.

But the product at this time has large ice crystals and is closer to frozen juice than ice cream. The first production of products with small and soft ice crystals like today was started by the royal chef of King Louis of France in 1774.

It was called cream ice at this time. Later, with the extensive use of condensed milk, condensed milk, milk powder and other raw materials, it began to be called ice cream. Then, ice cream was introduced to the United Kingdom and the United States via France, and gradually became known to people.

3. In 1851, in Baltimore, Maryland, USA, milk merchant JACOB FUSSEL realized the industrialization of ice cream. Established a factory in Baltimore, USA, and began mass production of ice cream for the first time. With the invention of the isobaric machine in 1899, the circulating refrigerator in 1902, and the continuous refrigerator in 1913, the industrialization of ice cream has developed rapidly around the world. The ice cream cone, on the other hand, made its debut at the 1904 St. Louis Everything's Fair.
