Place dough on a lightly floured board and press down on dough with the heel of your hand, punching the dough away from you. (If you dust your hands lightly with flour from time to time, it will prevent sticking.) Then fold dough over towards you; press down lightly and away from you. Give dough a quarter-turn to the left and repeat. Continue this procedure, folding and turning, for about 7 minutes, or until the dough feels elastic and the surface is satiny in texture. At this point it will no longer stick to the board or to your hands.
