Tools/materials: 200g mung bean, 0/00g rock sugar/kloc-0, and appropriate amount of clear water.

1 Wash and soak mung beans: Wash mung beans and soak them in water for about 2-3 hours until they become soft.

2. Boil mung beans: Pour the soaked mung beans into the pot, add enough water, and boil over high fire. After boiling, reduce the heat and continue to cook for about 30 minutes until the mung beans are cooked.

3. Add rock sugar: When mung beans are cooked to a certain extent, add a proper amount of rock sugar. Stir well with a spoon or blender until the rock sugar is completely melted.

4. Continue to cook: Continue to cook mung bean paste for about 10 minute until the crystal sugar is completely melted and mixed with mung beans.

5. Cooling and storage: pour the mung bean paste into a bowl and let it cool to room temperature before serving. If it needs to be preserved, you can put the mung bean paste in the refrigerator to keep the fresh taste.
