In a large bowl pour in warm water, add yeast and sugar and let sit for 2-3 minutes.
Then add olive oil, salt and 2 cups of flour mix then add another 2 cups of flour and continue to mix (dough will come together).
On a flat surface place the 1/2 cup of flour, remove dough from the bowl and knead in the 1/2 cup of flour, continue to knead till dough becomes smooth and springy. Lightly grease with olive oil a large bowl, place the dough in the bowl, roll dough so it is lightly covered with the olive oil then cover bowl completely with a towel. Let sit for approximately 1 1/2- 2 hours in a warm draft free area.
Then remove dough from the bowl and on a lightly floured surface knead for a minute, (if dough is sticky add a few drops of olive oil to your fingers). Then divide dough up and place in pizza pans and cover with desired toppings.
Pizza bianca:
On a small pizza crust drizzle the dough with olive oil, add rosemary and rock salt. Bake in 420 degree pre-heated oven for approximately 15-20 minutes (check after 13 minutes).
