Put approx. 1 teaspoon salt and oil on the edge of the flour and knead first with the dough hooks of the mixer, then with floured hands for 5-10 minutes.
Form the dough into a ball. Dust all around with flour and let it rise in the bowl covered in a warm place for 30-45 minutes until the dough volume has doubled and the dough looks porous.
Take the dough out of the bowl. Knead on a floured work surface with your hands for approx. 10 minutes to form a smooth dough. Whisk the dough on the work surface from time to time to allow the air to escape.

On the floured work surface, roll the small balls round (approx. 22 cm Ø) or the large ball rectangular (approx. 35 x 40 cm) or, even better, press them as flat as possible with floured hands.
Use your hands and fingertips to form an approx. 5 mm high rim. Continue with the tomato sauce and on the following pages with the recipes.
