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.

BLUEBERRY RHUBARB PIE

Steps:

• Heat oven to 425 degrees. Roll out both crusts. Line a deep 9-inch pie pan with the bottom crust and return both crusts to the refrigerator.
• In a medium bowl, combine rhubarb, berries, sugar, flour, tapioca, salt, nutmeg and lemon juice. Toss to coat and combine, then scoop into waiting bottom crust. The fruit should come up to within 1/2-inch of the rim of the pan; do not overfill. If necessary, add more or subtract some of the fruit. Break the butter into pieces and dot over the fruit.
• Lay top crust over filling. Trim excess dough from the edges and crimp, then cut 6 or 7 vents on top. Brush a light coating of egg wash over the crust, including the edges.
• Bake for 20 minutes. Reduce heat to 375 degrees. Bake another 25 minutes, then open the oven and quickly sprinkle the crust with a thin coating of granulated sugar. Bake another 10 to 15 minutes, or until you see steady bubbling in the filling coming through the vents.
• Remove pie from oven and listen to it: if the crust is sizzling, and the filling is audibly bubbling against the top crust, it is done. Let cool completely before serving.

BLUEBERRY-RHUBARB SLAB PIE

Steps:

• Prepare the pastry: In the bowl of a food processor, combine the flour, sugar and salt. Add the butter and pulse until the mixture is the texture of coarse sand with some larger pieces of butter. Drizzle in 1/3 cup ice water and pulse the mixture about 5 times or until the mixture is crumbly, but evenly moistened and holds together when you squeeze a bit in your hands. Add up to 3 more tablespoons ice water, but stop before the mixture becomes too wet.
• Tip the mixture out onto a large piece of plastic wrap. Using the plastic wrap, press the crumbs together. Divide the dough into thirds; tightly wrap one portion in plastic wrap, then combine the other two portions and wrap that larger piece of dough well in plastic wrap. Use a rolling pin to press both dough portions into two flat rectangles. Chill for at least 2 hours. (You can chill dough for up to 3 days in the fridge or freeze it for up to 3 months.)
• Meanwhile, prepare the filling: In a small saucepan, combine the rhubarb, 3 cups blueberries, the maple syrup and salt. Cook the mixture over medium heat, stirring occasionally, until the rhubarb has started to break down and the blueberries have started to release some of their juices, about 10 minutes.
• Transfer a few tablespoons of the liquid from the saucepan to a small bowl. Add the cornstarch and whisk until dissolved. Return the cornstarch mixture to the pan and cook, stirring, until the blueberry mixture has thickened, 2 minutes. Remove the pan from the heat and stir in the remaining 1 1/2 cups blueberries and the ginger. Let this mixture cool completely.
• On a lightly floured piece of parchment, roll the larger portion of dough into an 11-by-13-inch rectangle. Trim the edges into straight lines. Transfer the parchment with the dough to a rimmed baking sheet. Roll the smaller portion of dough out to a 7-by-15-inch rectangle on a floured piece of parchment. Using a fluted pastry wheel or a sharp knife, cut the dough lengthwise into seven 1-inch-thick strips.
• Spread the filling over the uncut rectangle, leaving a 1-inch border on all sides. Lay the strips of pastry over the filling on the diagonal, spacing the strips about 1/2 inch apart. Trim the strips so that they are even with the edge of the rectangle. Fold the edges up and over the filling and the strips and press the corners to seal. (Press with the tines of a fork, if desired.) Wrap lightly with plastic wrap and freeze for at least 30 minutes (and up to 2 hours).
• Heat the oven to 400 degrees. Using the parchment, transfer the chilled pie to another rimmed baking sheet. (You don't want to bake it on the cold sheet.) Brush the beaten egg all over the pastry and sprinkle with sanding sugar.
• Bake until the pastry is deep golden brown and the filling is bubbling in spots, 50 to 60 minutes. Transfer pan to rack to cool for at least 1 hour before slicing.
