1. Prepare the pot and stove. Copper pots are commonly used for cooking. If you can’t find it, you can also use an ordinary iron pot. Also prepare white sugar, water, bamboo skewers, spoons, etc. for use.

2. Put a copper pot on the fire, add an appropriate amount of water, and then add white sugar. The ratio of water to sugar is 2 to 1. That is to say, put two parts of water and one part of white sugar.

3. After placing the sugar, stir it gently with a spoon to help dissolve the sugar and prevent it from sticking to the bottom or burning.

4. Start heating over high heat to quickly increase the water temperature in order to dissolve the sugar in the water. Don't do this process too slowly. At this time, you can see that the sugar particles gradually become smaller until they disappear and completely become a sugar solution.

5. As the water temperature rises, the sugar liquid begins to stir. After the water boils, the water vapor begins to escape into the air. At this time, the temperature of the sugar liquid gradually becomes higher and the water in the sugar liquid gradually decreases. At this time, if you insert a thermometer into the sugar liquid, you can see that the temperature of the liquid exceeds 100 degrees Celsius. As time goes by, the temperature will increase and you can see that the sugar liquid begins to bubble. This is because there is less water in the sugar solution, and the tension in the sugar solution increases. During the discharge process, the air will form some big bubbles on the sugar surface. This process will last for a period of time. The main thing to note is that the heat should be stable, not too high or too low, and it should be turned regularly (every two or three minutes).

6. The temperature is not enough at this time. The appropriate temperature for boiling sugar is when the color turns slightly yellow and the big bubbles turn into small bubbles.

Origin

Emperor Guangzong of the Southern Song Dynasty was named Zhao Dun and his reign was "Shaoxi". During the Shaoxi period, Huang Guifei, Song Guangzong's favorite, fell ill. She is sallow, skinny, and doesn't want to eat. The imperial doctor used many expensive medicines, but they had no effect. The emperor saw that his beloved concubine was looking haggard and frowning all day long. In the end, I had no choice but to seek medical treatment. A charlatan entered the palace, diagnosed Huang Guifei's pulse, and said: "As long as you boil rock sugar and red fruits (hawthorn), and eat five to ten pieces before each meal, the disease will be cured within half a month." At first, everyone was doubtful. , Fortunately, this way of eating was suitable for the imperial concubine. After taking it according to this method, the imperial concubine recovered from her illness as expected. The emperor was naturally overjoyed and frowned. Later, this practice spread to the people, and people skewered it and sold it, which became candied haws.
