If you can’t get the dough to make a perfect circle, that’s okay! You’ll just end up with slightly uneven pieces. If you want the pieces to be as identical as possible: Roll the dough to about 13 inches. Take a cake pan, plate, or something else circular that’s about 12 inches wide and place it on the dough. Cut away the excess dough so you have a perfect circle left and proceed with the rest of the steps.
