Line a baking sheet with parchment paper. Combine filling ingredients together in a big bowl, leaving out the pears and cold butter for later.
Now toss the pears in the filling to coat.
Roll out the pastry crust on the baking sheet and pour 1/2 of the filling onto the center of each crust. From the outside, gently fold in the outer 2 inches. Fold crust in towards the middle, creasing about 6-7 times in the same direction.
Pat the cold butter onto the top of the pear filling.
Beat an egg and brush the outer crust with egg, then sprinkle with coarse sugar.
Bake at 400° F for about 20 minutes or until the crust is golden brown.
