In the bowl of a stand mixer fitted with a dough hook, stir together water, sugar and yeast. Allow to sit for 10 minutes. Stir in half the flour, olive oil and salt. Continue to knead with mixer, adding flour by the 1/4 cup until smooth and pulling away from the sides of the bowl, using a little less or a little more flour to achieve this. About 7 minutes. Place dough in an oiled bowl and cover with plastic wrap. Allow to double in size in a warm draft free area, about an hour. Punch down dough and divide into 5-6 equal portions approximately 125g each.
