Vanilla-Cardamom Pear Hand Pies

1. Add the pears, sugar, lemon juice, salt and cardamom to a medium saucepan over medium-high heat. Cook until the sugar is dissolved and the pears are starting to soften, about 8 minutes, stirring occasionally. Turn the heat off and stir in the vanilla bean paste. Set aside. Cool to room temperature, then refrigerate until fully chilled, about 1 hour (up to 3 days is fine).
2. When you want to make the pies, strain the pears, reserving the syrupy liquid for another use (such as a sweetener for tea, oatmeal, yogurt, etc.).
3. For the crust, whisk together the flour and salt in a large bowl and then cut in the butter with a pastry cutter or a fork until it looks like coarse meal. Add water 1 tablespoon at a time, working the dough together with your fingertips just until it comes together, and only adding enough water so the dough comes together when you squeeze it. Gather the dough together into a ball and then flatten it into a disk. Wrap it in plastic wrap and refrigerate until chilled, about 30 minutes.
4. Once chilled, remove the dough from the fridge. Lay a piece of parchment paper out on your work surface, place the dough on the prepared parchment paper, and top with another piece of parchment (or if you have it, freezer paper works even better because it’s thicker). Done this way, there is no need for flour to roll the dough out. Working from the center out, roll the dough out to a circle about 12 inches in diameter. Use a 4-inch cookie cutter (or a glass with that diameter) to stamp out circles in the dough.
5. Place a slightly heaping 1 tablespoon of pear filling in the center of each circle of dough. Use a thin metal spatula to lift up one circle of dough, then fold the dough over onto itself to form a half-moon, pressing the pastry closed along the outside. Set the pastry down on a flat surface and crimp the edges with a fork. Repeat with the rest of the dough circles. Then gather the scraps of dough, re-roll them, and repeat until the dough and filling are gone (you should get about 8 to 10 pastries). You can chill the dough scraps at any point if it becomes too difficult to re-roll them.
6. Chill the pastries in the fridge for 30 minutes. During this time, preheat the oven to 375 F.
7. Line a large baking sheet with parchment paper or a Silpat liner. Arrange the pastries on the tray and use a paring knife or fork to prick the top of each one or two times. Combine the egg and water in a small bowl. Brush the top of each pastry with the egg wash (you will have extra egg wash, don’t try to use it all) and sprinkle the 1 1/2 teaspoons of sugar on top (this amount is enough for all the pastries; you just need a little bit on each).
8. Bake until the pastries are golden and flaky, about 25 to 30 minutes.
