2. Boiling method: Before boiling, add vegetable oil into the interlayer of the sandwich pot, then pour the prepared sugar solution into the upper pot and boil it with high fire. When the sugar solution is boiled for 5-6 minutes, add 0.5 kg of saturated alum solution at room temperature, and mix thoroughly while adding. When the temperature of sugar solution measured by thermometer rises to 150℃, cease fire and cool. When cooking, the optimum temperature is 1 15 ~ 120℃.

3. crystallization method: put the sugar solution out of the pot into the pot and put it in the pit. The temperature in the pot was kept at about 90℃ that day, and then the temperature was reduced by 10℃ every day until the seventh day. If the temperature is not enough, fire can be added to increase the pit temperature. In general, sugar solution is neither afraid of cold nor heat during crystallization.
