What products did the "ancient milk tea shop" Bingjingwu in the Song Dynasty launch?

Every summer we all think about how nice it would be to have a glass of cool and refreshing ice water. In fact, in ancient China, our ancestors would produce some ice cubes to prevent heatstroke and cool down. Don’t think that our ancients were hardy against summer. Rich ancient people were actually very particular about it. They would choose to Go to some mountains and forests to escape the heat, eat some ice cubes, etc.

Bingjingwu is a special organization established in 962 AD. This organization is mainly responsible for the research and production of cooling foods. But this department basically serves the royal family. Sometimes the emperor will reward the food produced by Bingjingwu to his ministers when he is happy, but ordinary people basically cannot buy the things produced by this department.

But the heat is unbearable, and the products produced by Bingjingwu are not sold to ordinary people, so what should ordinary people do in summer? In fact, there were two businesses in the Song Dynasty that specialized in serving ordinary people. One was called "Cao Jia Congshi", and the name of the other one cannot be verified. These three departments actually produced ice and snow, cold syrup, licorice soup and Medicinal papaya and other cold drink products.

In fact, in addition to the production of "popsicles" in the Song Dynasty, their production methods are also relatively simple. In winter, you add the juice you want to add to a basin of water, freeze it outdoors for a day and it will basically take shape, then put it in an ice cellar, and you can sell it directly the next summer. . However, I think the popsicles produced in this way are definitely not as delicious as the current popsicles, but they are original. I don’t know what the taste is different from the current popsicles!
