Wash and drain glutinous rice. Place in a bowl with enough water to cover. Soak for at least 4 hours.
Syrup
Combine palm sugar and ¼ cup (60ml) water in a small saucepan. Bring to a boil and stir until sugar dissolves and thicken. This should take about 3 to 4 minutes. Turn off heat, remove, and set aside.
Sauce
Combine coconut milk, sugar, and salt in a small saucepan. Bring it to a bare simmer. Stir to dissolve sugar and salt. Do not allow it to boil. Turn off heat, remove, and set aside.
Steamed Sticky Rice
Fill pot for steaming with about 2 inches of water. Cover and bring water to a boil.
Line steaming rack with banana leaf. If you do not have banana leaf, use a dish instead. Drain glutinous rice and place onto banana leaf in steaming rack. Mix in salt. Stick cut pandan leaf into the rice. Place rack onto pot with boiling water. Cover and steam for 20 minutes over medium heat.
In the meantime, peel and cut mango into slices. Place on 4 individual or 1 large serving dish. Set aside.
When sticky rice is cooked, transfer to a bowl. Pour prepared coconut milk onto rice. Stir to mix. Rice may appear to be a little wet. Allow it to sit for 15 to 20 minutes and all the coconut milk will be absorbed.
To serve
Place a portion of cooked sticky rice beside the mango. Drizzle a little palm syrup over the rice.
