STRAWBERRY-RHUBARB SLAB PIE

Steps:

• Make crust: In a food processor, pulse flour, granulated sugar, and salt until combined. Add butter and 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; do not overmix. Divide dough into 2 disks, wrap each tightly in plastic, and refrigerate until firm, at least 1 hour (or up to overnight).
• Preheat oven to 400 degrees. Make filling: In a large bowl, toss together strawberries, rhubarb, granulated sugar, light-brown sugar, tapioca, and orange zest and juice.
• Lightly flour a work surface and rolling pin. Roll out 1 disk to a 12-by-16-inch rectangle. Transfer dough to a 10-by-14-inch jelly-roll pan. Press gently to fit into pan and fill with fruit mixture. Roll out remaining disk to an 11-by-15-inch rectangle. Place atop pie, pressing along edges to seal. Trim edges of dough, leaving 1 1/2-inch overhang all around. Fold overhang under, tucking it into pan. Crimp edges. Brush crust all over with egg-yolk mixture and sprinkle with sanding sugar, if desired.
• With a paring knife, cut slits on top to vent. Place pie in oven, then reduce temperature to 375 degrees. Bake until crust is deep golden brown and juices are bubbling in center, 55 to 65 minutes. Let cool on a wire rack, 1 hour. Serve warm or at room temperature.

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.

PEACH-BERRY RHUBARB SLAB PIE

Steps:

• Prepare the crust. In a medium bowl, stir together flour and salt until well combined. Add 1/3 cup butter and the shortening, then cut in with a pastry blender until flour appears crumbly and no crumbs are larger than pea size. Gradually add water, one tablespoon at a time, tossing thoroughly with fork after each addition until dough sticks together. Dough should be only slightly moist and should still retain a crumbly appearance until pressed together between fingers. Place mixture into an ungreased 9 x 13 inch glass baking dish and flatten to bottom, pressing dough halfway up the sides of the baking dish. Melt the remaining tablespoon of butter and brush over crust using a pastry brush. Immediately sprinkle with cinnamon and sugar and set aside.
• Make the filling. Peel and slice two of the peaches and place into a medium bowl. Add strawberries, blackberries, raspberries, and rhubarb. In a small bowl, combine 1 tablespoon flour and 2 tablespoons sugar, then pour over fruit and toss until fruit is evenly coated. Set aside.
• Preheat oven to 350 degrees. In a medium sauce pan, add remaining peaches (peeled and sliced), cinnamon, butter, corn syrup, honey, lemon jice, orange juice, and sugar. Begin cooking over medium heat, stirring constantly until juices form. Mix corn starch with 1 teaspoon of water and gradually pour into mixture while stirring constantly. Allow mixture to come to a boil. Continue to boil, stirring occasionally, until mixture thickens. Once thickened, stir constantly until the liquid portion of the filling sticks to the spoon when removed from the pan. It should almost have the appearance of cooled pie filling. Remove from heat and add remaining fruit, stirring juices into flour mixture before adding to the filling. Lightly stir to combine and set aside.
• Place empty pie crust in the oven on the middle rack and bake until the butter is melted and the cinnamon and sugar appear to have absorbed into the crust.
• In the meantime, prepare the streusel. In a medium bowl, combine all ingredients and stir together until crumbly and all dry ingredients appear a bit moist. Set aside.
• Remove crust from the oven and top evenly with pie filling. Cover with the streusel, paying special attention to the sides as the filling tends to bubble up over the topping along the edges. Bake on center rack for approximately 45 minutes, or until crust appears golden and streusel is crunchy. Remove from oven and cool, then slice into 12 pieces.
