1. Place the flours and salt in a stand mixer fitted with a dough hook. (Or knead by hand. I have not had luck making this in the food processor — the engine starts smoking after about five minutes.) Combine the water, sugar and yeast in a small bowl and let sit for five minutes until the mixture bubbles slightly. Add the olive oil and stir. With the mixer on low, gradually add the oil-water mixture into the bowl. Knead until the dough is firm and smooth, under 10 minutes. The dough will be very wet and sort of difficult to work with. I liberally coat my hands with flour before attempting to remove it.
2. Divide the dough into four balls, about 7½ ounces each. Line two cookie sheets with parchment paper. (Be sure to oil the parchment paper.) Place two balls on a sheet. Lightly rub the balls with olive oil, then cover loosely with plastic wrap. The dough is very sticky and wet, so, be sure to coat the balls or the plastic with oil. Let the balls rise in a warm spot until they have doubled in bulk, about two hours.
3. To roll out the dough: Dab your fingers in flour and then place one ball on a generously floured work surface. Press down in the center with the tips of your fingers, spreading the dough with your hand. When the dough has doubled in width, use a floured rolling pin (or continue using floured hands if you are skilled at making pizzas) and roll out until it is very thin, like flatbread. The outer portion should be a little thicker than the inner portion.

Note: This dough freezes beautifully. After the initial rise, punch down the dough, wrap it in plastic and place in a Ziplock bag. Freeze for several months. When ready to use, let sit at room temperature for about an hour, then proceed with rolling/topping/baking.

Baking

1. Preheat the oven to 500ºF. Line a sheetpan with parchment paper. Place rolled out dough onto parchment paper. Drizzle dough with a little olive oil and with your hand, rub it over the surface to coat evenly.
2. Top with a thin layer of your choice toppings. Here I used caramelized onions, grapes, gorgonzola and mascapone cheese. (The mascapone is really wonderful). Place in your very hot oven and bake for about 10 minutes or until the crust is slightly brown and the cheese is melting.
3. Remove from the oven and sprinkle with fresh basil. A drizzling of extra-virgin olive oil is nice. I used a little bit of truffle oil, which would be wonderful over a mushroom pizza.
