Perfect Pizza Dough

(my sister's recipe, yum!)

1 c. warm water
1 tsp. sugar
1 (1/4-oz) packet active dry yeast (or 2 1/4 tsp)
3 Tbsp. vegetable oil, plus extra for coating
2 1/2 c. flour, plus extra for dusting
1 tsp. salt

Place 1/4 cup of warm water in small bowl. Stir in the sugar until dissolved, then sprinkle yeast onto the surface of the water. Let yeast float there for 1 minute, then stir into water. Let yeast "proof" for 10 minutes. pour yeast mixture into large bowl and stir in remaining water, oil, flour, and salt. With wooden spoon, mix until the dough forms a ball. On a lightly floured surface, knead dough for 10 minutes or until smooth and elastic. Coat inside of large glass bowl with oil. Press dough into bottom of bowl and flip it over so oiled side is on top. Cover bowl with plastic wrap and let dough rise until doubled, about 1 1/2 hours. Pat dough out on greased pizza pan. Put on toppings and bake at 425*F for 15-20 minutes.
