After resting, knead the dough briefly and divide it into equal small balls (roughly golf ball size, or slightly smaller).
Flatten each ball with your palms into a small round disc.
Place a tablespoon of the cooled potato filling in the center.
Bring the edges of the disc up around the filling, pinching them together firmly. Gather and twist the excess dough at the top, then tear off the extra.
Remove the extra part and make it flat using hands.
Flatten the stuffed ball gently using your palm into a thick, even disc — about 1 cm thick.
Make sure no filling is exposed and the edges are well sealed.
