Black Bottom Hazelnut Pie Recipes

Steps:

• Make the crust: Stir together graham cracker crumbs, butter, sugar, and salt in a bowl. Press into bottom and up sides of a 9-inch pie plate. Refrigerate until firm, about 30 minutes. Preheat oven to 350 degrees. Bake until crust is set and begins to turn golden brown, about 12 minutes. Let cool completely on a wire rack.
• Make the filling: Sift together sugar, cocoa powder, cornstarch, and salt into a medium saucepan. Gradually whisk in milk. Cook over medium-high heat, stirring constantly, until almost boiling. Reduce heat to medium; add chocolate. Cook, stirring constantly, until chocolate has melted and mixture is thick, about 2 minutes. Remove from heat; whisk in butter and vanilla until smooth. Spread chocolate mixture over crust. Refrigerate until cold and firm, about 1 hour.
• Make the topping: Prepare an ice-water bath; set aside. Sprinkle gelatin over 2 tablespoons cold water in a small bowl. Let stand until soft, about 3 minutes. Whisk 1/4 cup sugar, the cornstarch, and salt in a medium saucepan. Gradually whisk in the milk. Cook over medium-high heat, stirring constantly, until mixture is thick and boiling, about 5 minutes. Remove from heat; stir in gelatin mixture, and let cool completely. Stir in vanilla and rum. Briefly place pan in an ice-water bath to thicken slightly, if needed. Do not let it set completely. Set aside.
• Put egg whites in the bowl of an electric mixer fitted with the whisk attachment. Beat on medium-low speed until soft peaks form. Reduce speed to low; continue beating while you make syrup.
• Bring remaining 1/2 cup sugar and 3 tablespoons water to a boil in a saucepan, stirring to dissolve sugar. Brush down sides of pan with a wet pastry brush to prevent crystals from forming. Cook, without stirring, until syrup registers 240 degrees on a candy thermometer.
• Raise mixer speed to high, and beat egg whites just until stiff peaks begin to form. Immediately pour syrup into egg whites in a slow, steady stream near side of bowl, avoiding whisk. Beat until glossy and cooled, about 7 minutes.
• Fold meringue mixture into reserved gelatin mixture in 3 batches until just combined. Mound the mixture into the chocolate-filled crust. Refrigerate pie for 2 1/2 hours or overnight before serving.

Steps:

• For the Crust
• Pulse granulated sugar, salt, and 1 1/4 cups flour in a food processor to combine. Add butter and pulse until coarse, pea-size crumbs form, about 10 seconds. With the motor running, add 2 Tbsp. ice water and process until dough just holds together, about 30 seconds. Squeeze a small amount of dough between your fingers: If it's very crumbly, pulse in more ice water 1 Tbsp. at a time (2 Tbsp. maximum). Do not overprocess.
• Turn out dough onto a lightly floured surface and push together into a ball. Knead a few times to combine, then flatten into a disk with smooth edges (no cracks). Cover tightly and chill at least 1 hour.
• Roll out dough to a 13" round on a lightly floured surface. Roll dough loosely around rolling pin and transfer to a standard 9"-diameter pie dish. Lightly press dough into pan, leaving a 1" overhang; trim excess. Fold overhang under and crimp as desired. Chill until cold, about 30 minutes.
• Do Ahead: Dough can be made and shaped into disk 3 days ahead. Keep chilled, or freeze up to 3 months. Thaw before rolling.
• For the Filling and Assembly
• Place racks in bottom third and center of oven; preheat to 375°F. Place a rimmed baking sheet on bottom rack to preheat.
• Spread hazelnuts on another rimmed baking sheet and bake on center rack until light golden brown, about 10 minutes. Reserve 1 cup whole hazelnuts to decorate pie; finely chop remaining hazelnuts.
• Melt chocolate in a small heatproof bowl set over a small saucepan of barely simmering water (do not let water touch bowl); stir constantly until chocolate is melted and smooth. (You can also do this in a microwave.) Remove from heat and let cool slightly. Spread chocolate in bottom of pie shell with the back of a spoon and chill until set, about 15 minutes.
• Melt butter in a small skillet over medium heat or in a microwave in a microwave-safe bowl. Pour butter into a large bowl. Whisk in brown sugar, espresso powder, vanilla, 1 cup corn syrup, and 3/4 tsp. salt until well incorporated. Whisk in eggs, then fold in chopped hazelnuts.
• Pour filling into pie crust (do not overfill). Toss whole hazelnuts with remaining 2 Tbsp. corn syrup and 1/4 tsp. salt in a small bowl and arrange on top of pie. Place pie dish on preheated baking sheet on bottom rack and bake 20 minutes. Rotate baking sheet, move to center rack, and continue to bake, covering edges with foil or a pie shield if crust starts to brown too much, until crust is golden brown and filling is almost set with a slight jiggle in center of pie, 20-25 minutes more. Transfer pie to a wire rack and let cool before slicing, about 3 hours.
• Do Ahead: Filling (before decorating) can be made 1 day ahead. Bring to room temperature before baking. Pie can be made 2 days ahead. Cover loosely with foil and store at room temperature.
