Onto a lightly floured work surface, roll the dough to a rectangle of about 15 cm X 45 cm. Fold the top third down to the center, then the bottom third up and over that. If necessary brush the excess flour. Turn it to the left or right and roll out again to three times the length. Repeat the rolling and folding for a total of 4 to 6 times. If the dough gets sticky during the process refrigerate for 30 minutes and continue.
