Sift the flour into a bowl and add the dry yeast. Make a hole in the middle and add the yeast dissolved in hot water. Add the salt and the olive oil and then alternate adding hot water and flour to make the dough. Knead the dough until soft. Set aside, cover with a cotton towel or wrap and leave in a warm place until it doubles in volume. When the dough rises, knead flat. Cut the dough into tangerine-size pieces and roll into long bars and place on a cotton towel.
