1In a large bowl proof the yeast with the sugar in 1/3 cup lukewarm water for 10 minutes, or until it is foamy.
2Stir in an additional 1/3 cup lukewarm water, oil, 2 cups flour, and salt and blend mixture until it forms a dough.
3Knead the dough on a floured surface, incorporating as much of the remaining 1/4 cup flour as necessary to prevent the dough from sticking, for 5 to 10 minutes, or until it is smooth and elastic.
4Alternatively, the dough may be made in a food processor.
5Proof the yeast as de scribed above and in a food processor combine it with the remaining ingredients.
6Process the mixture until it forms a ball, adding more water, 1 teaspoon at a time, if it is too dry, or more flour, 1 tablespoon at a time, if it is too wet, and knead the dough by processing it for 15 seconds.
7Put the dough, prepared by either method, in an oiled bowl and turn it to coat it with the oil.
8Let the dough rise, covered with plastic wrap, in a warm place for 1 hour, or until it is double in bulk, and punch it down.
