Step 1

Boil the sweet potatoes in hot boiling water for 15 minutes, or until the inside is cooked through. Peel the skin off and discard. Smash the sweet potatoes.

Step 2

Add the mashed sweet potatoes with flour, sugar, and water to form a dough that is not sticky to the hands.

Step 3

Divide the dough into small, equal portions and roll them into balls. Roll the sweet potato balls with sesame seeds.

Step 4

Heat up a shallow pot with 2-3 inches oil. When the oil is fully heated, deep fry the sweet potato balls until golden brown. Dish out and drain well on paper towels. Dust with powdered sugar before serving.
