What should I pay attention to when I want to open an ice cream shop?

Ice cream is a delicious frozen dairy product with great temptation. Nearly 8 years ago, ice cream originated in China. The expansion rate of hard ice cream is 8%-1%, and it is hardened to facilitate packaging and transportation. Created by Italians, it is mainly processed in factories and frozen in stores for sale, so it can be seen from the appearance that it is hard and the particles of ice inside are coarse. Soft ice cream has no hardening process in the production process, and the expansion rate is 3%-6%. Generally, it can be made and sold by ice cream machine. Usually, a soft ice cream contains more nutrients (about 1.6 times) than a hard ice cream with the same volume; Soft ice cream without hardening will also be more creamy and mellow. Soft ice cream was made by Joseph of England in the 193s. Invented by Lyon Food Company. Margaret Thatcher, the former British Prime Minister who worked as a pharmacist in the company at that time, also participated in the development of soft ice cream emulsifier.
