Spread some flour over a board, or directly onto the work surface you are using, if it's clean. Put some flour on your hands, to stop the dough sticking to your hands or the work surface.

Remove the dough from the bowl and knead it with your hands until it is smooth.

Sprinkle out some more flour, and use a rolling pin to roll out the dough until it is quite thin (about 2-3 mm thick). Keep putting flour on the rolling pin as you do this, to stop the dough from sticking to it.
