Mangoes are available almost all year long in Thailand and there is never a shortage of rice. Here is a sinful dessert that joins the two. I know rice is rarely considered a dessert food, but this is a delicious treat. Coconut sticky rice can be eaten with any fruit and is great by itself. Thai sweet rice, not jasmine, is used to make this dish. What makes the rice stick together is its high starch content. Sweet rice is actually steamed instead of simmered. I use a traditional bamboo steamer insert for this. In the United States, Manila mangos are in season for 3 to 4 months out of the year, their extra sweetness and soft texture make them a perfect accompaniment to the coconut sticky rice.
