Soak the glutinous rice for at least 6 hours, up to overnight.

Steam the rice for 20 minutes (place uncooked rice in cheesecloth, then steam using any type of steamer)

In a small saucepan or pot, heat coconut milk over medium heat. As it starts to boil, add the sugar and salt. Stir till the sugar and salt have dissolved. Set aside about ¼ cup of the coconut milk mixture for serving later.

Put the steamed glutinous rice into a large mixing bowl. Pour the remaining coconut milk over the rice. Stir the coconut milk into the rice until evenly distributed.

Serve the mango and the sticky rice together. Garnish with sesame seeds. Drizzle the additional coconut milk onto the rice or mango if desired.
