In a medium sized bowl,mix mango juice and the sugar until well dissolved

Add in the rice flour slowly until well blended

Por mixture in to a pan and steam for 20 mintues

While waiting, peel the mango and cube it for filling

Test for doneness when a toothpick inserted in the middle comes out clean

take pan out and cool for 10 mins

spread butter onto wide working surface and hands to avoid the dough from sticking to the work surface and hands

while still warm, scoop thr dough out of the pan with a spoon covered in butter and roll inyo medium size balls.

flatten the dough ball and place a mango cube in the middle

close the ball tightly and place on a plate that is dusted with cornstarch

repeat until all of the dough is used

lightly brush the balls with water and then gently sprinkle the shredded coconut onto the balls

note: when rolling the balls from the dough, this part is the hardest. it is very sticky and some what difficult to work with. the cooler the dough is, the harder the dough will be to work with. u can use more butter or cornstarch to make it less sticky and cut the dough into medium pieces to make it easier to roll.
