Start by cooking the rice. Line the bamboo steamer with banana leaves. Add the soaked rice in the centre, cover and place on top of a boiling pot of water. You can also use a steamer insert if you don’t have a bamboo steamer. Or simply cook the rice in the pot of boiling water, the texture in this case is mushier, so keep stirring. Let it steam for 20 minutes.
Meanwhile, lets start with your coconut sauce. Add the coconut milk to a shallow pan. On medium heat combine the sugar with the coconut milk, make sure to not boil it. Taste and adjust sugar according to your taste.
Remove from heat and divide this coconut sauce into 3 equal parts. We will use 1 to give the rice the last cook, the second would be incorporated into the rice post cooking. And the third would become the sauce we use for topping.
Use one third of the sauce, add cornflour to it and stir on low heat to make a thick slurry. Keep aside.
Carefully remove the bamboo steamer from the pot of water. Add 1/3rd of the coconut sauce and mix well. Steam for another 10 minutes.
Remove and dish out the rice into a bowl. Add the remaining coconut sauce to the rice and mix well until combined.
Peel the mangoes and dice into cubes or slice.
Serve with fresh, sweet mangoes, topped with sweet coconut sauce, white and black sesame seeds and fried moong dal.
