There are many theories about the origin of ice cream. As far as the west is concerned, it is said that when Alexander the Great made an expedition to Egypt around the 4th century BC, he preserved the winter snow in the Alps and used it to freeze and eat fruit or juice, thus enhancing the morale of soldiers. It is also recorded that Palestinians use ice and snow in caves or canyons to drive away the heat. Among all kinds of statements, the most convincing one started with China. 1292, after traveling in China, Kyle Poirot wrote "Oriental Notes", which recorded that he brought his favorite formula of frozen milk back to Venice and spread it in northern Italy. The traditional frozen food from the East was introduced to the West by Kyle Poirot, and further developed and industrialized, thus giving birth to today's ice cream. The frozen milk that China began to eat a long time ago was introduced to the west by Kyle Poirot, but it is as popular all over the world as it is today. At about 1660, it was the first coffee shop to open in Paris. After Italian Cotelli mixed orange juice and lemon juice to make juice, he frozen the juice and sold it. But at this time, the product has large ice crystals, which are closer to frozen juice than ice cream. The first product with small and soft ice crystals like today was made by 1774, the chef of King Louis of France. It's called cream ice at this time. Later, with the widespread use of concentrated milk, condensed milk, milk powder and other raw materials, it began to be called ice cream. Then, ice cream was introduced to Britain and America through France, and was gradually recognized by people. ★ 185 1 year, in Baltimore, Maryland, USA, Jacob forssell industrialized ice cream. He set up a factory in Baltimore, USA, and started mass production of ice cream. With the help of 1899 homogenizer, 1902 circulating refrigerator and 19 13 continuous refrigerator, the industrialization of ice cream has developed rapidly all over the world. On the other hand, ice cream cones made their debut at the 1904 World Expo in St. Louis. In the first century BC, the Greek king Alexander led an army into Persia (now Iran). In Iran, due to the intense heat, some soldiers suffered from heatstroke, which greatly weakened the combat effectiveness of the troops. "What can I do? Yes, go to the mountain and get some snow! " The soldiers mixed fruit juice and grape juice into the snow, stirred them and drank them all at once. "It's so comfortable!" Later, when the Roman emperor Nero was in the heat, he also learned the method invented by Alexander, and asked his servants to retrieve ice and snow from the nearby mountains and add honey and juice to quench their thirst. This is a precedent for ice cream making. The real making of ice cream with cream began in China. 1295, Kyle, an official in China Yuan Dynasty? 6? 1 Polo brought back an iced food formula of fruit, snow and milk from China, and then a new breakthrough was made in cold drinks in Europe. 1550 or so, Italians put ice and snow in a basin, and then put wine or juice in the ice and snow to cool it to clear away heat and relieve summer heat. There is a Nancy in 1846? 6? 1 Johnson invented the crank ice cream machine. When making, add some salt or potassium nitrate to the ice and snow to lower the temperature of the ice and snow, and then add milk, eggs, sugar and so on. Put it in a small bucket and keep stirring. After a while, the ice cream will be ready. From then on, people can make ice cream at home. 1904 in San Diego, USA? 6? During the Lewis/KLOC-0 World Expo, some people folded pancakes baked with eggs, milk and flour into cones and put ice cream in them for participants to taste. Soon, this kind of ice cream cone became popular all over the world. Looking back at history, 2000 BC ... history (history)
