To mix the base ingredients I use the dough hook attachment on my food mixer or food processor but it can easily be mixed by hand.
Put the flours in a large bowl and add the yeast and the salt. Don’t add these together as the salt will kill the yeast. I add to opposite sides of the bowl. Make a well and pour in the water and olive oiland bring together until you have a slightly wet dough.
If using a food mixer this will only take a few minutes, otherwise turn onto a lightly floured dough and knead for 5 minutes until the dough is smooth and slightly springy.
Cover with a tea towel and leave the dough to rest for 5 minutes until smooth and slightly springy.
Divide into 4 rounds, roll out thinly and carefully place onto floured baking sheets.
