Into a large bowl, sift the 3 cups flour. Make a well in the middle of the flour and add the yolks, egg, salt, 2 tablespoons olive oil and milk. With your hands, begin mixing the eggs in the middle of the well, slowly incorporating the flour. Mix until all the flour is incorporated. The dough should be firm and dry. Add more flour if necessary till mixture forms a ball. Knead 5 minutes. Wrap dough in plastic wrap and refrigerate for about 30 minutes.
