DOUBLE CRUST APPLE BUTTER PIE

Steps:

• To mix the dough by hand: In a large bowl, whisk together the flour and salt. Add the butter cubes, tossing them through the flour until each piece is well coated. Cut the butter into the flour by pressing the pieces between your palms or your fingers, flattening the cubes into big shards and continuing to toss them through the flour, recoating the shingled pieces.
• For a flaky crust, continue cutting the butter into the flour just until the pieces of butter are about the size of walnut halves.
• Make a well in the center of the flour mixture. Add 6 tablespoons ice water and mix to incorporate. Then add more ice water 1 tablespoon at a time and continue mixing just until the dough comes together. As it begins to come together, you can knead it a few times to make sure it's fully combined. It's important not to add too much water to the dough, which should never be sticky--it should hold together easily in a ball but still feel almost dry to the touch.
• Divide the dough in half and shape into 2 equal disks. Wrap tightly in plastic wrap and chill for at least 30 minutes or up to overnight.
• Lightly flour the work surface. Roll out one disk of the dough to a circle 1/4 inch thick: Start in the center of the disk of dough and push away from you using even pressure. Return to the center and repeat, this time moving toward you. Continue, rotating the dough occasionally and reflouring as needed to prevent the dough from sticking. This produces a more even result than just rolling back and forth, which can often yield thin edges and a thick center.
• To transfer the dough to the pie pan, roll the dough up onto the rolling pin, starting at the far edge of the round. With the pie pan in front of you, start at the edge closest to you and gently unfurl the dough into the pan. Press gently to make sure the crust settles all the way to the bottom, but be careful not to poke any holes in the dough. Trim away the excess dough, leaving a 1/2-inch overhang all around. Chill in the refrigerator for 20 to 30 minutes or freeze for 5 to 10 minutes.
• Roll out the second disk of dough on a lightly floured surface to 1/4 inch thick and place on a parchment-lined baking sheet. Chill in the refrigerator for 20 to 30 minutes or freeze for 5 to 10 minutes.
• Make the filling: In a medium bowl, whisk together the apple butter, sugar, and eggs until well combined. Pour into the chilled bottom crust.
• Roll the top crust up onto the rolling pin, starting at the far edge of the dough. With the pie pan in front of you, start at the edge closest to you and gently unfurl the dough onto the filling. Use your fingers to press the edges of the bottom and top crusts together so they are lightly sealed. Trim the excess dough from the edges, leaving a 1/2-inch overhang all around. Tuck the excess dough under at the edges, pressing lightly to help "seal" the dough to the outer rim of the pie pan.
• Crimp the edges of the piecrust as desired. I refrigerate the pie for 20 to 30 minutes.
• Preheat the oven to 425 degrees F (218 degrees C), preferably with a baking stone on the bottom rack.
• Make the egg wash: In a small bowl, beat the egg with the water and fine sea salt.
• Brush the top crust with the egg wash and sprinkle generously with turbinado sugar. Use a small sharp knife to cut a dew small vents in the crust. Bake the pie on the stone or bottom rack until the crust is deeply golden and the filling is bubbling up through the vents, 40 to 45 minutes. If the crust begins to brown too quickly, reduce the oven temperature to 375 degrees F (190 degrees C) and/or tent the crust or edges with foil. Cool the pie for at least 30 minutes before serving.
