In the bowl of a stand mixer, or in a large bread bowl, dissolve the yeast in the water. Add the sugar and stir together. Let sit 2 or 3 minutes, until the water is cloudy. Stir in the olive oil.
Using a stand mixer: Combine the flour and the salt, and add to the yeast mixture all at once. Mix together using the paddle attachment, then change to the dough hook. Knead for 10 minutes. Hold on to the machine if it bounces around. Turn out onto a clean work surface and shape the dough into a ball.
As soon as you can scrape the dough out in one piece, turn it out onto a lightly floured work surface, and knead for 10 minutes, adding flour as necessary, until the dough is firm. Shape into a ball.
Transfer the dough to a clean, lightly oiled bowl, rounded side down first, then rounded side up. Cover the bowl tightly with plastic wrap and leave it in a warm spot to rise for 1 to 1 1/2 hours, until doubled.
Weigh the dough and divide it into 3 equal balls. Shape each ball by cupping it between your hands, with the bottom of your hands touching your work surface, and moving the dough in a clockwise circle between your hands, working round and round the dough until it becomes a ball. Put the balls on a lightly oiled baking sheet, cover with lightly oiled plastic wrap or a damp towel, and leave them to rest for 15 to 20 minutes.
