Cut the pumpkin into small cubes and place in a pot.
Then rinse the pearl barley and place in a pot.
Rinse pandan leaves and add to the pot. Twist a few times to release the aroma.
Add water. Bring the water in the pot to a boil. Then reduce the heat to low, cover with a lid and simmer for 2 hours until the pearl barley is soft and slightly chewy.
Add sugar to taste. Cook for another 5 minutes or so until the sugar dissolves. Serve warm or chilled.
