Rinse the mung beans thoroughly under cold water.
Place them in a bowl and cover with water. Let them soak for about 2 hours. This will soften the beans and help them cook faster.
After soaking, drain the mung beans and rinse them under cold water.
Bring a pot of water to a boil. Add a pinch of salt if desired.
Add the mung beans to the boiling water and cook until they are soft but still hold their shape. The beans should be tender but not mushy.
Once cooked, drain the beans and spread them out on a clean kitchen towel or paper towel to remove excess moisture.
Heat a small amount of oil in a pan over medium heat.
Add the cooked mung beans and fry them until they are crispy and golden brown. This step is optional but adds a delightful crunch to the sticky rice.
Once fried, remove the beans from the pan and place them on paper towels to drain any excess oil.
Let the mung beans cool completely. Once cooled, they can be stored in an airtight container until ready to use.
When serving the mango sticky rice, sprinkle the prepared mung beans over the top of the sticky rice for added texture and flavour.
