Moon cake is a traditional food in China, and the ice-covered moon cake is one of its many varieties. The white skin is made of glutinous rice, and the finished moon cake needs to be frozen in the refrigerator, so it is called ice-covered moon cake.
Frozen moon cakes were originally a traditional Mid-Autumn Festival food in Vietnam. They were introduced to China and Hong Kong from Vietnam in the 1980s. At that time, Hong Kong taipan bread cake was popularized after learning its practice, which changed the traditional moon cake market and became popular among Chinese all over the world. It also made Hong Kong taipan frozen moon cakes synonymous with frozen moon cakes.
Because the ice-covered moon cakes need to be frozen, they were only sold in Hong Kong at that time. It was not until 2007 that many large import and export companies in Shenzhen introduced them to the mainland from Hong Kong and promoted them nationwide, so that the ice-covered moon cakes could come into our lives. However, many people go to Hong Kong specially to buy large-scale iced moon cakes.
