To make the pizza dough, put the flours, yeast, salt and sugar in a large bowl and mix together. Make a slight well in the middle and add the oil, yogurt and water and carefully mix together into a dough. It will be slightly wet and sticky. Tip the dough out onto a floured surface and knead for about 5 minutes, stretching the dough away from you with the back of your hand, folding the stretched part over on top of the rest of the dough, turning 90 degrees then repeating. Add a little more flour as you go, if needed. After around 5min it should stop feeling sticky. Clean out the mixing bowl, lightly oil it then form the dough into a ball and put it in the bowl. Cover with cling film/plastic wrap and leave it to rest somewhere warm for about an hour, possibly more, until it doubles in size.

When ready to make the pizzas, preheat oven to 425F/220C. Put baking sheets in the oven to allow them to pre-heat.

Knock back the pizza dough (prod with your fingers after turning it out of the bowl) and divide into 2 (alternatively, you can make one large pizza or more smaller). Keep the piece(s) you are not working with to one side, covered, while you work on the one pizza.

Roll out the pizza dough into a circle or rectangle, as you prefer, and as suits your baking sheet/tray. Roll it about as thin as you can and transfer to a piece of parchment paper. Repeat with the remaining dough.
