Vanilla ice cream

Ice cream has been in our country for millennia, and has since been brought back to Italy by Marco Polo with this Chinese skill and the ancient formula, evolving into various forms of ice cream in the current world, thanks to continuous improvements in Europe. In my country's ancient history, the ice snacks used for this summer food were not called ice cream, but “ice cream”. It is also simple, first made from milk, by boiling the milk, then pouring it into a copper basin and making it taste good fruit or sugar, then putting it into a large wooden basin, into which ice is poured into the proper amount of salt, ice is rapidly melted in contact with salt, so that it can reach 5 or 6 degrees Celsius in a moment, immerse the copper basin in the tub, and the milk is frosted on the wall of the copper basin, where it is convulsed with wood spoons, which condens the ice repeatedly decomposition within half an hour, cuts a piece of it into a bowl with a knife and so on. These ice creams are usually only available to the Emperor or the rich, because they are too expensive and expensive! In our ancient era, we had the technology to store ice blocks during periods of proprietorship. According to the ancient history of the translation, the ice is stored deep in the pits of the earth, which are laid under four walls with round logs covered with straw, and in the winter when ice is taken, the ice is coded and covered with straw, so that the ice is not melted until autumn, as it is available. In the past, kings, officials or merchants used these ice blocks in the summer to freeze meat or fruit-like foods, and it was said that the twigs which the Princess Yang used in that year were delivered from the south to Changan by means of 800-mile relays, which were then stored in an icebox. Later, it was not until Tang Song that the ice cellar was created, and now there are ancient ice cellar sites in Beijing's North Sea Park and Palace, which you may wish to prove. In Europe, I've seen old ice cream machines kept at foreigners' homes. This ice cream machine, in fact, is a small oak drum 50 cm in diameter, 30 cm deep, with a copper-made metal drum in its middle, much smaller than a barrel, about 20-25 cm in diameter, where the drums are salted with ice, then the milk used for ice cream is poured into the metal drums, and the interior of the metal drums, which are scraped manually and without interruption, will soon condensate the milk, which is said to be the ice cream machine created by the Chinese practice when Marco Polo returned. Here's a quick way to make ice cream. The raw materials I use are fresh milk, eggs, sugar, solid cream and two drops of vanilla, which is called vanilla ice cream, which is very good, as follows:
