In a medium mixing bowl or food processor, blend yeast, water and teaspoon of flour. Foam should form on surface in about 8 minutes (if not, yeast is past its prime; find fresher). Then blend in rest of flour and salt, forming a smooth, quite soft, slightly sticky dough. Blend in food processor no more than 30 seconds (then knead 5 minutes by hand); in mixer blend for about 5 minutes; by hand stir to blend and knead 5 minutes.
Place in a large oiled bowl, cover bowl with plastic wrap. Let stand in a cool place until doubled in bulk (about 1 1/2 hours). If not ready to bake, keep dough covered and hold up to 8 hours. About 20 minutes before baking, punch down, knead a minute or two and then form into a ball, cover.
To make pizza, lightly oil a 14- to 16-inch pizza pan. Preheat oven to 500 degrees F, setting rack as low as possible in oven. Roll out dough as thin as possible to about a 16-inch round (no more than 1/16-inch thick). Spread over pan, rolling in edges to form a rim. Let rest 10 minutes.
Top as desired or suggested below and bake 10 minutes. Then, using a spatula and thick oven mitt, slip the pizza off the pan directly onto the oven rack by pulling out rack, grasping pizza pan firmly with protected hand, and using spatula or pancake turner to slip pie off pan and onto rack. Slide rack back in place and bake 2 minutes. Slip pie back onto pan, remove from oven. Cut and serve.
In a 10-inch skillet heat 1 tablespoon oil over medium high. Sauté onion and parsley to golden, then stir in garlic and oregano for a few seconds. Add tomatoes, crushing them as they go into the pan (do not substitute crushed tomatoes). Boil, stirring, 5 minutes or until thick.
Spread sauce over rolled out crust, sprinkle with basil, mozzarella, and finally the oil. Finish with generous black pepper and a little salt. Bake as directed above.
In Naples, fresh or canned tomatoes often replace tomato sauce on pizza. Make sure tomatoes have big, rich flavor and use them judiciously.
Use any of the following flavorings sparingly, but only enough to flavor, not overwhelm: Sliced red onion, pitted olives, pepperoni, anchovy, sliced mushrooms, steamed broccoli or cauliflower, salami, prosciutto, roasted peppers, shrimp, cooked Italian sausage, hot pepper, fresh herbs such as marjoram, oregano, mint, garlic, rosemary or sage. For "Americanized" pizza, use tandoori marinated chicken breasts, oven roasted vegetables, salsa and anything else you desire.
