ABOUT THIS RECIPERice that soaks up the coconut sauce
Khao niao mamuang brings together three distinct elements: sticky rice, coconut milk and ripe mango. The rice is soft and slightly sticky, the coconut milk rich and subtly salty, and the fruit adds juiciness and fresh sweetness. That contrast is what makes the dessert complete. Use real sticky rice, also sold as glutinous rice or sweet rice; ordinary jasmine rice will be fragrant, but it lacks the characteristic cohesive bite.
Rinsing and soaking are important for even cooking. Rinse the rice until the water is mostly clear, then soak it for at least four hours. Drain it, then steam it over boiling water rather than boiling it in a pot of water. Steaming lets the rice absorb moisture without the grains at the bottom becoming wet and mushy. A bamboo basket is handy, but a metal steamer insert lined with a clean cloth works too; keep the rice above the water.
Gently heat the coconut milk with the sugar and salt, just until the sugar has dissolved. Boiling it hard can cause the sauce to split or stick to the pan. Stir some of it into the hot rice and leave it covered for a while to absorb the liquid. The grains will become glossy and creamy, but should hold their shape. Full-fat coconut milk makes a rich sauce. Coconut cream works too, but it is thicker; thin it with a splash of water if needed.
Choose a mango that smells fragrant and yields slightly to gentle pressure, but is still firm enough to cut neatly. That way, the fruit stays juicy and fresh alongside the warm, soft rice. Mangoes are generally imported in the Netherlands, and availability and ripeness vary by season and shop. If a fruit is still hard, let it ripen at room temperature. Another ripe, juicy mango can replace the variety specified; very soft fruit is less suitable because it quickly falls apart on the plate.
Serve the rice lukewarm or at room temperature with the mango and the reserved coconut milk. Cut the fruit just before serving so the pieces keep their shape. This is a rich dessert; small portions are nice after a meal, or set the platter out for everyone to share. Sticky rice is best eaten the day it is made. Store leftovers covered in the fridge and eat them within two days; gently reheat the rice with a small splash of water and serve with freshly cut mango.
