In a small bowl, dissolve the yeast and sugar in 1/4 cup of the water. Set aside until foamy, about 5 minutes.
Into a large bowl, sift 5 cups of the flour and the salt, and make a well in the center. Pour the yeast into the center well and mix the yeast into the flour, working in the remaining water. Turn out onto a lightly floured surface and knead into a soft, pliable dough. Continue working the dough until it is smooth and shiny, 10 to 15 minutes, adding more flour as necessary. Knead 2 tablespoons of the oil into the dough and work the dough over itself into a smooth ball. Pour the remaining tablespoon of oil into a large bowl. Place the dough in the bowl, cover with a damp kitchen cloth, and let rise in a warm, draft-free spot until doubled in size, about 1 1/2 hours.
Preheat the oven to 450 degrees F at least 30 minutes before baking. Lightly oil a heavy baking sheet.
Punch down the dough and lightly knead for 2 minutes. Divide into 8 to 12 equal portions, depending upon your preference, and roll into balls. Flatten and roll with a rolling pin to about 1/4-inch thickness. Place on a lightly floured surface, cover with a lightly floured kitchen cloth and let rise until doubled in size, 30 to 40 minutes.
Transfer to the prepared baking sheet and bake until puffed and golden, about 5 minutes. Turn and bake on the second side, about 4 minutes. Remove from the oven and let cool on wire racks. Repeat with the remaining dough.
