Whisk together flours, 1 teaspoon salt, and 1 teaspoon sugar in a large bowl. Add butter and rub the mixture with your fingers until it resembles cornmeal with pea-size balls of butter. Bit by bit, add ice water and gently mix with your hands until the dough begins clumping. Place on a lightly floured work surface and knead for 1 minute, or until dough forms a ball. Wrap in cling wrap and refrigerate for at least 1 hour.
Heat the oven to 350°F.
On piece of parchment paper on a flat surface, roll the dough into a 12-inch circle, about 1⁄8-inch thick.
Combine remaining salt, sugar, and spices in a large mixing bowl. Add pears and toss until coated.
Arrange pear slices in the center of dough, leaving a 2-inch border. Break cheese into small pieces and divide on top of pears, then sprinkle with hazelnuts.
Slide the parchment onto a baking sheet and bake for 30 minutes, or until golden brown.
