Place potato chunks into a pot of salted water and boil until fork-tender, about 15–20 minutes. Drain thoroughly and mash until smooth.

In a mixing bowl, combine the mashed potatoes with glutinous rice flour, water, and sugar. Stir until a smooth, elastic dough forms.

Divide the dough into small, equal-sized portions and shape each into a ball.

Transfer the fried mochi to paper towels to absorb excess oil.
