150 g (1 cup) sweet potato, cubed
75 g (½ cup) glutinous rice flour
4 tbsp water, or more
50 g (½ cup) grated coconut
½ tsp salt
FILLING (Mixed together)
60 g (½ cup) roasted walnuts, pounded
40 g palm sugar, grated
TO PREPARE SKIN:
Steam the sweet potato until soft. While hot mash the sweet potato in a large mixing bowl. Add the flour and enough water to form a smooth dough that does not stick to your hands.
Roll into small balls. Flatten a ball in your palm. Put some walnut filling in the middle and seal it. Roll it back into a ball.
TO PREPARE TOPPING:
Mix the grated coconut with the salt and steam for 2-3 minutes and let it cool completely.
Bring a pot of water to boil. Cook the glutinous rice balls in the boiling water – it’s done when they float to the surface; remove them with a slotted spoon.
Roll onde-onde in the grated coconut.
