How to Make It
In a glass measuring cup, sprinkle the yeast over the warm water. Stir in the sugar; let stand until foamy, 5 minutes.
In a large bowl, mix 2 cups of the flour with the salt. Add the yeast mixture and stir until smooth. Add the remaining 3 cups of flour and stir until a stiff dough forms. Turn the dough out onto a lightly floured surface and knead until smooth and elastic, about 5 minutes. Transfer the dough to a large bowl lightly brushed with olive oil.
Cover the dough with plastic wrap and let rise in a warm, draft-free spot until doubled in volume, about 1 hour.
Punch down the dough and knead it 3 times. Divide the dough into 6 pieces and roll into balls. Transfer to a lightly floured baking sheet and cover loosely with plastic wrap.
