How to keep rock sugar? Generally speaking, people buy a lot of rock sugar from the beginning of the dog days, so as to save them in case of emergency. How can we keep the rock sugar from deterioration?
According to legend, during the reign of Emperor Kangxi in Qing Dynasty, there was a girl named Fusang, who was the maid of Zhang Yaxian, the owner of a big sugar workshop in Neijiang, Sichuan.
Once, while Zhang Yaxian was not there, she scooped out a bowl of syrup and was ready to drink it. When Zhang Yaxian came, Fusang quickly poured the syrup into the pig oil tank, hid it in the wood pile, and put some chaff on it to cover it.
A few days later, when Fusang took out the pig oil tank, it was filled with many crystal like things. It was crisp and pure sweet, and its taste was better than sugar.
Fusang talked about this strange phenomenon, and many people concocted it as they did. Because the sugar produced was like ice and tasted like honey, people called it rock sugar.
Storage method:
1. Because rock sugar is easy to absorb water and get damp, it should be placed in a cool and ventilated place.
2. If you find that the crystal sugar is affected by moisture, you can dry it with an electric fan or expose it to the sun until it is dry.
Editor's note: if you find that the surface of rock sugar turns to water (i.e. relatively sticky), it is not easy for the family to deal with it, and it is easy to breed bacteria, so it is better not to eat it.
