1 Combine the yeast, flour, and 2 teaspoons salt in the container of a food processor. Turn the machine on and add 1 cup water and the 2 tablespoons of oil through the feed tube.
2 Process for about 30 seconds, adding more water, a little at a time, until the mixture forms a ball and is slightly sticky to the touch. If it is dry, add another tablespoon or two of water and process for another 10 seconds. (In the unlikely event that the mixture is too sticky, add flour, a tablespoon at a time.)
3 Turn the dough onto a floured work surface and knead by hand a few seconds to form a smooth, round dough ball. Grease a bowl with the remaining olive oil, and place the dough, in it. Cover with plastic wrap or a damp cloth and let rise in warm; draft-free area until the dough doubles in size, 1 to 2 hours. You can, cut this rising time short if you are in a hurry, or you can let the dough rise more slowly, in the refrigerator, for up to 6 or 8 hours.
4 Proceed with any recipe below, or wrap the dough tightly in plastic wrap and freeze for up to a month. Defrost in a covered bowl in the refrigerator or at room temperature.
To make this dough by hand: Combine half the flour with the salt and yeast and stir to blend. Add 1 cup water and: the 2 tablespoons olive oil; stir with a wooden spoon until smooth. Add remaining flour a bit at a time; when the mixture becomes too stiff to stir with a spoon, begin kneading, adding as little flour as possible-just enough to keep the dough from being a sticky mess. Knead until smooth but still quite moist, about 10 minutes. Proceed as above.
To make this dough with a standing mixer: The machine must be fairly powerful or it will stall. Combine half the flour with the salt, yeast, 2 tablespoons olive oil, and 1 cup water; blend with the machine’s paddle. With the machine on slow speed, add flour a little at a time, until the mixture has become a sticky ball that pulls away from the sides of the bowl (switch to die dough hook if necessary). Knead for a minute by hand, adding as little flour as possible, then proceed as above.
