Stir together the water and the sugar, then stir in the yeast. Let stand in a warm spot until foamy, about 10 minutes.
Combine 2½ flour, salt, and 1 T olive oil, then work the foamy yeast in.
Flour your kitchen counter, then turn the dough out onto it. Knead until smooth, about 10 minutes. If the dough is very sticky, add a bit more flour. If it’s dry, add some water.
Oil the large bowl, drop in the dough, and turn it so that it is coated with oil.
Cover with plastic wrap or a towel, set in a warm place, and let rise for about 1 hour, until it doubles in size.
Punch down the dough and let it rest for 5 minutes. Divide it into the desired number/size of pizzas, and roll each into a ball. Cover with towels.
Sprinkle the pizza pan or stone with cornmeal or flour.
Roll each ball into a flat disk with a slightly raised edge, then on the pizza pan. Add toppings and bake according to your pizza recipe.
