Extraordinary Pizza Crust

Description
This is a recipe I obtained from an Estate sale. I obtained it when I purchased the family collection from the Konder Estate in Dallas, Texas in 1991.

Ingredients

 * 1 tablespoon dry yeast
 * ½ teaspoon sugar
 * 2⅔ cups warm water
 * 2 tablespoons olive oil
 * 7½ cups unbleached all purpose flour
 * ¼ cup whole wheat flour
 * 1 tablespoon coarse salt

Directions

 * 1) Proof the yeast for 10 minutes in 1 cup of warm water and a pinch of sugar until yeast dissolves and liquid begins to appear creamy.
 * 2) Add remaining water and 2 cups flour including the whole wheat flour.
 * 3) Beat this well until it's smooth and soupy then let it stand for 15 minutes until it is bubbly and swollen.
 * 4) Add salt and olive oil and proceed to stir in the rest of the flour by the cupful until the dough is stiff but still slightly sticky.
 * 5) When dough begins to form a cohesive mass thick enough to hold its shape then turn out onto a lightly floured surface and let it rest.
 * 6) Meanwhile clean and oil the bowl.
 * 7) Knead dough turning it clockwise by quarter turns and sprinkling a little flour on top and on the surface underneath before folding it over.
 * 8) Add just enough flour so the dough doesn't stick and tear.
 * 9) When dough is smooth return it to the oiled bowl and cover with a damp cloth.
 * 10) Let it rise until doubled then it is ready for use.
