Bring to boil rinsed black glutinous rice, water and pandan leaves.
Lower heat to medium-high, and keep cooking and stirring often, for 40 minutes (or until black glutinous rice turn into porridge texture).
Add in palm sugar syrup and sugar, simmer until the water almost evaporated, then add in salt.
Take off from heat, and stir to cool a bit.
Pour some into serving bowls/cups, top with coconut milk and serve.
