In a small bowl, dissolve sugar and yeast in warm water. Let stand until creamy, about 10 minutes.

In a large bowl, combine the yeast mixture with flour; stir well to combine. Stir in additional water, 1 tablespoon at a time, until all of the flour is absorbed. When the dough has pulled together, turn it out onto a lightly floured surface and knead briefly for about 1 minute.

Lightly oil a large bowl, place the dough in the bowl and turn to coat with oil. Cover with a damp cloth and let rise in a warm place until doubled in volume, about 30 minutes.

Preheat oven to 475 degrees F (245 degrees C).

Deflate the dough and turn it out onto a lightly floured surface; knead briefly. Pat or roll the dough into a sheet and place on a lightly greased baking sheet. Brush the dough with oil and sprinkle with salt.
