In a small bowl, whisk together 11⁄2 cups (360 grams) warm water, yeast, and sugar. Let stand until foamy, 5 to 10 minutes.

In a large bowl, whisk together flour and salt. Add yeast mixture and oil, and stir until combined and a dough forms. Cover and let stand at room temperature for 15 minutes.

Turn out dough onto a lightly floured surface, and knead by hand until smooth and elastic, 5 to 10 minutes. Shape dough into a smooth round.

Lightly oil a large bowl. Place dough in bowl. Cover and let stand in a warm, draft- free place (75°F/24°C) until doubled in size, about 1 hour.
