Sprinkle the 2 tablespoons flour over a clean surface (such as a kitchen counter or breadboard). Put dough on surface. Shape dough into a ball, using floured hands. Knead dough by folding and pushing with the palms of your hands, then make a quarter turn. Repeat these steps to knead 5 to 10 minutes or until dough is smooth and elastic. Wrap dough tightly in the plastic wrap.
