Durian Glutinous Rice Balls 榴槤糯米糍

Got this recipe from my Aunt but she said 'how to make' instructions need to keep it private (secret recipe) and cannot share with you, sorry!!! Therefore, I can only post out the ingredients here.

(makes 55-60pcs)
454 g Glutinous rice flour 糯米粉
2 Tbsp oil
1-2 Tbsp sugar (according to your taste)
3 Cups water
1/4Cup cooked glutinous rice flour or fine coconut powder (My friends do not like coconut so I use cooked glutinous rice flour for outside layer of the rice ball)
Frozen durian meat (cut in small pieces). Keep frozen for easier for wrapping.
