Dough
2 1/2 pounds (about 8 cups) all-purpose flour
1 pound (about 3/4 cup) whole wheat flour
1/4 cup powdered sugar
1 tablespoon granulated sugar
2 tablespoons salt
1/4 cup shortening
4 cups water

Toppings
Grated Parmigiano-Reggiano cheese
Poppy seeds or black or white sesame
    seeds or cumin seeds
Dried herbs such as oregano or marjoram
Fresh herbs such as rosemary leaves,
    marjoram and lavender
Cayenne pepper
Fresh chopped garlic
Sea salt and pepper

In a large bowl, combine both flours, powdered sugar, sugar and salt; mix in shortening. Add water and mix and knead the dough until it's smooth and supple, about 6 to 8 minutes. Divide into 12 (8-ounce) portions, shape each piece into a ball, flatten into a disk, wrap tightly in plastic wrap and refrigerate overnight or at least 2 hours.

Preheat oven to 400 degrees F. Remove dough from refrigerator and flatten one piece with your hand on a floured work surface. Using a rolling pin, roll out as thinly as possible into an oval shape, dusting the surface as needed. (Alternatively, use a pasta machine to roll out the dough to attain a very thin sheet of dough.) Lightly oil the back of a cookie sheet or spray it with cooking spray.

Drape the thin sheet of dough over the back of the oiled pan. Brush with olive oil. Sprinkle with your choice of toppings such as cheese, seeds, fresh or dried herbs, garlic, cayenne, sea salt and pepper. Repeat with remaining pieces of dough.

Bake one at a time in preheated oven until deep golden brown and crisp. The time needed will depend on the thickness of the dough.

Cool and serve, breaking it into crisp shards.
