1. Prepare the ingredients and wash the plums. If the plums you buy are sweeter, then the sugar will be reduced. If it is sour, the amount I gave is just right.

2. Cut the plums into small pieces.

3. Put the plums in the juice machine, add water, lemon juice and rock sugar, and crush.

4. Pour into the pot and boil, then turn to medium heat and slowly boil.

5. It took me about half an hour to cook until the sauce was thick. Pay special attention to boiling bubbles during the boiling process, pay attention to safety, do not burn your hands.

6. After cooling, put it in a small bottle without water and oil, store it in the refrigerator.
