Mangga't suman (mango and sticky rice wrapped in coconut leaves) is a popular snack and dessert combination. The sweetness of ripe mangoes goes well with the blandness of the native delicacy making them perfect partners.
Just like taste, it still is subjective, for I like eating my ibos just with sugar and separate from ripe mangoes. Though for this blog post I have no other choice but to eat them as they were "meant" to be - lol. But they are not as weird as the other in(famous) combo of what else - champorado and tuyo.
