Dough: Combine water and sugar in processor. Sprinkle yeast over; let stand until foamy, about 10 minutes. Add oil, then 3 cups flour and salt. Process until dough comes together, about 1 minute. Turn dough out onto floured work surface. Sprinkle with rosemary. Knead until dough is smooth and elastic, adding more flour by tablespoons if dough is sticky, about 5 minutes. Lightly oil large bowl. Add dough; turn to coat with oil. Cover bowl with plastic, then towel. Let stand in warm draft-free area until dough doubles, about 1 hour.
Punch down dough. Knead dough in bowl until smooth, about 2 minutes.
Bread maker can also be used for this on dough cycle. Follow general pizza crust instructions for rising after dough cycle completes.
