Place a pizza stone on the bottom rack of oven and preheat to 500 degrees F. for 45 minutes to 1 hour. Dissolve the yeast in the warm water and let stand for 10 minutes. Traditional method: Put 1 1/2 cups of the flour, semolina sugar and salt in a large mixing bowl. Stir to combine. While stirring with a wooden spoon slowly add the yeast mixture until combined. Add the olive oil and continue stirring until the mixture forms a loose ball, adding the remaining 1/4 cup of flour if necessary to form a ball that is not sticky. On a lightly floured board knead the dough for 3 to 5 minutes until the dough is smooth and consistent in texture.
Food Processor method: With the metal blade inserted, put the flour, semolina, sugar and salt into the work bowl. With the motor running, pour the yeast mixture through the feed tube and process for 30 to 45 seconds or until the dough pulls away from the sides of the bowl. Add the olive oil through the feed tube and continue to process for 1 minute. The dough should have formed a ball. Turn the dough onto a lightly floured surface and knead briefly with flour until it is not sticky.
Both methods continue: Form the dough into a ball and put in a bowl that has been lightly coated with olive oil. Cover the bowl with a damp towel and put it in a warm place until doubled in size, about 1 hour. Roll the dough on a lightly floured surface into a cylinder and cut into 6 equal pieces. Roll each piece into a ball and place on a lightly floured platter. Cover with a damp towel. Using a rolling pin, roll one ball into a circle. Garnish the pizza as desired. Place directly on pizza stone and bake for approximately 4 minutes (Check after 3 minutes) until ready.
Continue creating individual pizzas.
