crusty pizza dough

This pizza dough is one of CJ's (few) specialties in the kitchen.  It's definitely cheap to make, but once we add ingredients, I'm sure it would cost just as much to buy a frozen pizza.  It'd be quicker too, but definitely not as good.

Crusty Pizza Dough
KitchenAid (the cookbook came with our mixer)

1 package active dry yeast
1 cup warm water (105-115 degrees)
2 tsp. salt
2 tsp. olive oil
2.5 - 3.5 C. all-purpose flour
1 Tbsp. cornmeal

Dissolve yeast in warm water in warmed mixer bowl.  Add salt, olive oil, and 2.5 C. flour.  Attach bowl and dough hook to mixer.  Turn to speed 2 and mix about 1 minute.  Continuing, add remaining flour, 1/2 C. at a time, and mix about 2 minutes, or until dough clings to hook and cleans sides of bowl.  Knead on Speed 2 about 2 minutes longer.  Place dough in greased bowl, turning to grease top.  Cover and let rise in warm place, free from draft, about 1 hour or until doubled in bulk.  Bake at 450 for 15-20 minutes.
