Sprinkle the 2 tablespoons flour over a clean surface, such as a kitchen counter or breadboard. Put dough on the surface. Divide dough in half to make 2 balls. Roll each ball of dough around 3 or 4 times. Curve your fingers around and fold dough toward you, then push it away with the heels of your hands, using a quick rocking motion. Repeat 10 times. Put bowl upside down over balls of dough for 15 minutes.
