To shape the buns, take each dough ball and roll it out into a cigar-like shape. Next, roll it out into a longer and narrower strip, and fold it in half lengthwise. Roll it up into a bundle, with the loose end tucked underneath. Turn it on its side so the swirls are facing up, and press it down with your palm. Now roll it out into a disc about 4 inches in diameter. Repeat these steps for all of the dough balls. (See the picture to see how to shape the dough).
