BLUEBERRY SLAB PIE

Steps:

• Stir together the blueberries, lemon zest and lemon juice in a medium pot. Begin to heat over medium heat, stirring occasionally, until the berries begin to burst, 3 to 5 minutes. Use a potato masher to smash the berries a couple times at the beginning to help encourage the process.
• Stir together the sugar, cornstarch and salt in a small bowl. Sprinkle this mixture over the berries and stir well to combine. Continue to cook over medium-low heat, stirring constantly, until the mixture begins to thicken and bubble from the center of the pot, 2 to 3 minutes.
• Stir in the butter and vanilla until well combined. Cool the filling completely. (The filling can be made up to 2 days ahead; store in an airtight container in the refrigerator.)
• On a clean, dry work surface, gently roll out one of the sheets of puff pastry with a rolling pin to flatten it, flouring the surface only if necessary. Gently transfer the dough to a shallow 9-by-13-inch pan (such as a quarter baking sheet) pressing firmly into the base and edges and allowing the excess to hang off the sides. Pour the cooled filling into the crust and spread in an even layer. Chill while you prepare the remaining dough.
• Roll out the second sheet of puff pastry the same way. Gently transfer to the top of the pie and press the edges firmly all the way around to seal and flatten slightly. Gently fold the edges of the crust under itself all the way around. Use a fork or your fingers to crimp and seal the pie.
• Chill the pie in the refrigerator while you preheat the oven to 400 degrees F with a rack in the lower third (if you have a pizza stone, place it on the rack).
• Whisk together the egg and water in a small bowl. Brush the egg wash mixture over the crust, focusing on the center portion rather than the edges, which tend to brown enough on their own. Sprinkle turbinado sugar evenly over the pie. Cut a few vents into the center of the pie with a paring knife.
• Transfer the pie to the oven (on top of the pizza stone if using). Bake until the pie is deeply golden brown and the filling bubbles through the vents, 35 to 40 minutes. Cool at least 1 hour before slicing and serving.

BLUEBERRY CRUMBLE PIE

Steps:

• For crust:
• Pulse 1 1/4 cups flour, butter, and salt in a food processor until mixture resembles coarse meal with some pea-size pieces remaining. Drizzle 3 tablespoons ice water over mixture. Pulse until moist clumps form, adding more water by teaspoonfuls if mixture is dry. Transfer dough to a lightly floured work surface. Divide into 4 equal pieces. Working with 1 piece at a time, use the heel of your hand to smear each portion of dough twice in a forward motion to distribute butter. Gather all 4 dough pieces into a ball. Flatten into a disk, wrap in plastic, and chill dough until firm, at least 1 hour.
• Roll out dough on a lightly floured surface to a 13" round. Transfer to pie dish, gently pressing dough onto bottom and up sides of dish. Fold overhang under and crimp edges decoratively. Pierce bottom of crust in several places with a fork, then chill until firm, about 30 minutes.
• Line a large baking sheet with foil and place on a rack in middle of oven; preheat to 375°F. Line crust with parchment paper or foil and fill with pie weights. Bake until crust is set, about 20 minutes. Carefully remove parchment and pie weights. Bake until crust is pale golden, about 12 minutes longer. Transfer crust to a wire rack; let cool.
• Filling and topping:
• Whisk 2/3 cup sugar, cornstarch, and lemon zest in a large bowl. Add blueberries and lemon juice; toss gently to coat and evenly distribute. Let filling stand, tossing occasionally, until berries release their juices, 20-30 minutes.
• Whisk flour, remaining 3 tablespoons sugar, light brown sugar, cinnamon, and salt in a medium bowl. Add melted butter; mix topping with fingertips to blend.
• Assembly:
• Preheat oven to 375°. Spoon blueberry filling into crust, then sprinkle topping over. Bake pie until filling is bubbling and topping is golden, about 1 hour 15 minutes. Cover with foil after 30 minutes if browning too fast.
• Let pie cool on a wire rack.
• Do Ahead
• Dough can be made up to 2 days ahead. Keep chilled. Pie can be baked 8 hours ahead. Let stand at room temperature.

BLUEBERRY SLAB PIE

Steps:

• In a large, flat-bottomed bowl, combine flour, sugar, and salt. Add the butter cubes and toss to coat with the flour mixture. Use a pastry blender to cut the butter into the flour; do not smash or smear the butter. Scrape butter off the pastry blender during the mixing process and continue mixing. (If butter is softening too fast, put the bowl in the refrigerator until butter firms up, 2-5 minutes.) Continue cutting, working quickly, until butter is broken down and looks like a coarse crumble with only a few larger pieces.
• Combine vinegar with water and ice; you'll use up to 1½ cups of this liquid in the pie dough, a tablespoon at a time. Begin by sprinkling about 8 tablespoons of liquid over the flour mixture; use a bench scraper or your hands to incorporate until the mixture begins to come together. Sprinkle in 8 more tablespoons of liquid and continue the mixing process. Squeeze a fistful of dough: if it holds, like wet sand, it's ready. If it falls apart, add 1-2 more tablespoons of liquid at a time, squeezing the dough to check if it holds. Bring all the dough together, sprinkling dry bits with more small drops of liquid as necessary; dough will look shaggy. Knead in the bowl just until incorporated.
• Turn dough onto a work surface and use a bench scraper to divide dough into two equal pieces. Shape into flat disks and wrap in plastic; refrigerate for at least 30 minutes, preferably overnight. Dough can be refrigerated for up to 3 days and frozen up to 1 month, tightly wrapped.
• Generously butter a baking sheet and line with parchment paper. Dust a large work surface and tapered French rolling pin with flour. Roll out 1 disc of chilled pie dough into a rectangle by rolling it in an "X," diagonally, for even stretching. (If dough is softening too fast at any point in the rolling process, chill in the refrigerator until firm, 2-5 minutes.) Once the dough has been thinned out, switch to a straight French rolling pin and continue rolling the dough until it's a rectangle of even thickness, 3-4 inches larger than the baking sheet. Fit the dough into the baking sheet by gently folding in half, then in half again. Align the creases squarely in the middle of the pan, then unfold the dough so it's centered in the pan. There should be a 1-inch dough overhang on all sides. (If necessary, it's okay to stretch the dough gently.) Repeat the rolling and shaping process with top crust dough to a 17" x 13" rectangle. Invert a rimmed baking sheet and spread the dough on top. Refrigerate both sheets while assembling the filling, 20 minutes.
• Filling: Taste your blueberries first. They can vary from really sweet to really tart which will affect how much sugar is added; add or take out up to ¼ cup sugar to adjust sweetness. In a small bowl, mix shredded apple with lemon juice. In a large bowl, combine both sugars, Angostura bitters, allspice, cloves, cinnamon, cardamom, salt, and ground arrowroot. Add the blueberries, crushing about half of them with your hands; mix well to combine, making sure no spices remain at the bottom of the bowl.
• Preheat oven to 425 F. Remove the chilled dough sheets; set the top dough aside. Transfer the filling into the dough-lined baking sheet, patting it down to make sure there are no gaps. Use the round pastry cutter to punch random holes into the top dough, 2-3 inches apart, to create a polka dot effect; don't get too close to the edges. (Save the pastry circles to make crust cookies!) Place the top dough sheet squarely over the filling, then seal the top and bottom crusts by tucking and pinching excess dough under the bottom crust. Seal again by pressing circumference of crust with your thumbs.
• Brush egg wash evenly over the top crust, and sprinkle with raw sugar. Pie will bake for a total of 1 hour. Bake on the lowest rack of the oven until crust is set and beginning to brown, 20-25 minutes. Lower heat to 375 F, move the pie to the center oven rack, and continue to bake until crust is a deep golden brown and juices are bubbling throughout, about 30-35 minutes longer. Allow pie to cool completely on a wire rack before cutting into it, 1-2 hours. Serve slightly warm or at room temperature.

BLUEBERRY SLAB PIE

Steps:

• Make crust: In a food processor, pulse flour, salt, and sugar until combined. Add butter; pulse until mixture resembles coarse meal, with a few pea-size pieces of butter remaining. With machine running, add 1 cup ice water. Pulse until dough is crumbly but holds together when squeezed (if necessary, add up to 1/2 cup water, 1 tablespoon at a time). Do not overmix. Divide dough into 2 disks; wrap each tightly in plastic. Refrigerate until firm, at least 1 hour (or up to overnight).
• Preheat oven to 400 degrees. Make filling: In a large bowl, toss together blueberries, cornstarch, sugar, and lemon zest and juice. On a floured work surface, roll out 1 disk to a 12-by-16-inch rectangle. Place in a 10-by-14-by-1-inch rimmed jelly-roll pan. Pour in blueberry filling, then lightly brush edges of crust with water. On floured surface, roll out second disk to an 11-by-15-inch rectangle and lay over blueberry filling; press along moistened edges to seal. Fold overhang under, tucking it into pan, and crimp edges. With a paring knife, cut slits on top to vent.
• Place pie in oven, then reduce heat to 375 degrees. Bake until crust is golden and juices are bubbling, 50 minutes. Let cool on a wire rack 1 hour. Serve warm or at room temperature.
