Sticky Rice with Mangoes (Kao Niow Mamuang)

Place rice in a large bowl. Add enough water to cover by 3"; soak for 3 hours, then drain.

Fill a wok with water and bring to a boil over high heat. Fit with a bamboo steamer, add rice, reduce heat to medium-low, and steam until rice is tender, 20–25 minutes. Transfer rice to a bowl and set aside.

Place coconut cream in a medium saucepan (if using canned coconut milk, spoon cream off the top). Add sugar and salt. Bring to a boil over medium-high heat and cook, stirring, until sugar dissolves, about 1 minute. Pour over rice, mix well, then set aside until liquid has been absorbed, about 30 minutes. To serve, spoon rice onto 6 plates and garnish with mangoes.
