Take out the dough and knock it back. Divide the dough into six equal portions, approximately 200g each.
Shape into rounds and place the dough onto a generously floured baking tray.
Cover the dough with a clean tea towel and allow to prove for about 60 to 90 minutes.
Preheat the oven to its highest setting and place a large flat baking tray turned upside down to heat.
Transfer one of the rolled dough balls to a nicely floured work counter.
Using your fingertips, flatten out the dough and stretch it to the desired size.
