Prepare the Sweet Potatoes: Start by peeling the sweet potatoes and cutting them into evenly sized pieces.

Cook the Sweet Potatoes: Boil the pieces in water until tender, then drain and let them cool slightly.

Make the Dough: In a mixing bowl, mash the cooked sweet potatoes and gradually add glutinous rice flour until you achieve a dough-like consistency. If the dough is too dry, add milk little by little until it comes together easily.

Shape the Balls: Take small portions of the sweet potato dough and shape them into balls. Continue until all the dough is used.

Fry the Sweet Potato Balls: Heat oil in a frying pan or a deep fryer over medium heat. Fry the balls until golden brown and crispy.

Drain and Serve: Remove the balls from the oil and let them drain on a paper towel-lined plate. Optionally, while still warm, roll them in sugar for a sweet finish.

Enjoy: Serve the crispy sweet potato balls warm and savor the delightful flavors.
