Make the sticky rice by simmering coconut milk and a little sugar over low heat. Add the hot sticky rice and stir until well combined and sticky.

Shape the sticky rice from step 1 into small balls. Press 1-2 pieces of mango into the center of each ball (you don't need to use all the mango).

Place the shaped sticky rice and mango in the refrigerator for about 1-2 hours to chill and set.

Arrange the sticky rice balls on a plate, top with mango, drizzle with coconut sauce, and serve!
