Peel and roughly diced 1 small rustic potato and boil it in water until it has softened. Drain the water and mash the potato chunks well. Measure out 64g to be used later.
In a blender, add in the cut pandan leaves and 1 cup of water. Blend until the pandan leaves are blended finely. Pour the blended pandan water over a cheesecloth that's been placed over a sieve and a bowl. Squeeze out as much pandan water as you can. Discard the blended leaves and reserve the pandan water. Save 1 cup of the pandan water for the batter.
In a bowl, add in the glutinous rice flour, rice flour, baking powder, salt, and sugar. With a whisk, mix well. Then add in the mashed potato, shredded coconut, and the 1 cup pandan water. Knead well until you get a pliable dough. Set aside.
Place 1/2 cup of RAW white sesame seeds into a bowl. Set this next to the pandan dough.
Grab about 1/2 TBSP of the dough and roll it into a ball. You can make it as little or as big as you want. So grab as much dough as you feel. Place the ball into the bowl of sesame seeds. Roll it around until it has fully been covered. Shake off any excess seeds and place onto a plate or sheet tray. Repeat until all the dough is used up.
Heat enough vegetable oil in a deep pan to 325' F and gently place half of the rolled up balls into the pan. Gently move them around so they don't stick to the bottom and let it fry for at least 6-8 minutes. You'll know they're done when they turn golden brown and have floated to the top. Remove them with a spider onto a colander and finish frying the other half.
Once all the balls are fried, let it cool for 5 minutes before enjoying them! They're best when they're still crispy.
If you want, you can dip these sesame balls in some sweetened condensed milk :)
