In a large bowl, using a wooden spoon, or in a stand mixer fitted with the dough hook, combine the flour, sugar, yeast and salt. Add the water and mix just until the dough starts to form a ball. Knead the dough with your hands for 5 minutes on a lightly floured work surface, or with the dough hook, just until smooth.
Form the dough into a ball and place in a clean, lightly oiled bowl, turning to coat with the oil. Cover with a damp cloth and let rest in a warm, humid spot for 2 hours or until doubled in volume.
