2, put a little water in the pot, put rock sugar (white sugar), slowly cook until the rock sugar melts, and slowly start to pop up big bubbles after melting.
3. The big bubbles slowly turn into small bubbles, and the color gradually turns yellow, so it is necessary to keep stirring on the way.
When the sugar turns yellow, turn off the fire and use chopsticks to test whether it meets the requirements. When the color turns light brown, immerse chopsticks in syrup, quickly immerse them in cold water, and then take them out. If the sugar is solidified and chews hard, the cooking is successful.
5. Precautions:
(1) You can put oil or water in boiling sugar, if the water is slightly different.
2 Sweet potatoes should not be eaten with persimmons, tomatoes, liquor, crabs and bananas.
③ Patients with gastric ulcer, hyperacidity and diabetes should not eat it.
