Rinse the glutinous rice under cold water until the water runs clear. This removes excess starch and prevents the rice from becoming too sticky.
Soak the rinsed rice in water for at least 4 hours or overnight for best results. After soaking, drain the rice.
Steam the rice using a bamboo or metal steamer lined with cheesecloth for about 25-30 minutes, or until the grains are translucent and tender.
While the rice is steaming, combine the coconut milk, sugar, and salt in a small saucepan. Warm over medium heat, stirring until the sugar dissolves. Do not let it boil; remove from heat once combined.
Once the rice is cooked, transfer it to a bowl and pour about 1 cup of the sweet coconut milk mixture over the hot rice. Mix well and let it sit for about 15 minutes to absorb the flavors.
To serve, mold the sticky rice into a shape or serve in a small bowl next to the sliced mango. Drizzle with additional coconut sauce over the top.
Garnish with sesame seeds and fresh mint leaves if desired.
Notes
Serve the sticky rice and mango on a vibrant plate, with the coconut sauce drizzled artfully around.
