Preheat the oven to 450°. Line a baking sheet with parchment paper and set aside.
In a small bowl, mix together the sugar and spices and set aside.
Peel the pears with a vegetable peeler and slice in half vertically. Use a melon baller to scoop out the seeds and discard. Sprinkle the pears on both sides with the sugar and spice mixture and set aside.
Roll out the pastry dough and cut into four equal pieces (top to bottom and side to side so that you have 4 pizza pie looking pieces of dough (I use a pizza cutter to cut the dough). Place one pear, flat side up on the pastry with the stem end facing the point.
Use the pastry cutter to trim about 1" of excess dough from the bottom of the "crust side of the pizza slice". Place the trimmed piece toward the top one-third of the pear. Wrap the bottom portion of the dough around the pear and seal it by pinching it together with your fingers. If it doesn't completely surround the pear, that's ok. You just want it to hold together.
Transfer the pastry wrapped pear, flat side down to the baking sheet. Continue with the remaining pears
Brush the outside of the pastry dough with egg wash. Bake for 25-30 minutes or until pastry is golden brown and pears are softened. Remove from oven and let rest for 5 minutes before transferring to plates to serve. Great with ice cream or whipped cream!
