With each colour, take a tiny bit of the dough and form them into small balls with your fingers. I like them small so I recommend a diameter of 1cm. They can be left out to dry without covering.
Make the coconut sauce by simmering the coconut milk in low-medium heat. To the pot, add lemongrass and Pandan leaves that have been tied into a knot. Leave the sauce to infuse for at least 20 minutes.
Make the syrup by dissolving sugar in the water and bring to simmer then poach the egg in the syrup. Fish out the egg and set aside.
Next, we'll cook the glutinous rice balls by first removing the herbs from the coconut sauce and turn up the heat to medium.
Then add the colourful glutinous rice balls to cook in the coconut sauce. They will float as soon as they're cooked, this should take about 2-3 minutes depending on the size of the balls.
To serve, make sure it's warm then dish out the glutinous rice balls with coconut and place the sweet poached egg on top.
