2) Measure out 440ml warm water (it should be pleasantly warm on your wrist). Sprinkle the yeast on top of the water and allow it to activate, about 10 minutes.
3) Put the salt and 280g of the flour into a food processor. Pulse five times to blend. Pour in the yeast and water and pulse five more times. Add the olive oil. Add the remaining flour, 1 cup at a time, pulsing and scraping the sides of the bowl until well blended. As soon as the mixture is combined, dump it out onto a well-floured board and knead for 15 turns. The dough will become smooth and elastic-like.
3) Place the dough in a greased bowl and turn to coat all sides. Cover with clingfilm or a tea towel. Allow the dough to rise in a warm place for 45 minutes, until doubled in size, and then punch it down.
4) Divide dough in half; each half will make one pizza. You can make two pizzas or freeze half the dough for another time. Freeze the dough in a resealable freezer bag. To thaw, remove the bag from the freezer and place in the refrigerator for 24 hours. Roll the dough out while cold and then allow it to come to room temperature before adding toppings.
