How to make
Knead a dough from half the flour, the sugar, salt, yeast and the corn flour. Sift the remaining flour in and knead the dough until elastic and finally add the oil.
Cover the dough with a towel and leave it in a warm place until doubled in volume. Make 1 large, or 2 medium pitas from the dough, and if desired, make lines along the length. Cover the pitas again and leave them for another 30 minutes.
