Hazelnut Crunch Recipes

Steps:

• Line a heavy large baking sheet with parchment paper. Stir the sugar, water, light corn syrup, and dark corn syrup in a heavy large saucepan over medium heat until the sugar dissolves. Increase the heat to high and boil without stirring until a candy thermometer registers 260 degrees F, about 20 minutes. Reduce the heat to medium-low. Mix in the hazelnuts, butter, and salt (the mixture will be thick and nutty), and cook until the thermometer registers 295 degrees F, stirring constantly, about 15 minutes. Quickly stir in the baking soda. Immediately pour the caramel onto the prepared baking sheet, spreading it as thinly as possible. Let stand until hard.
• Break the brittle into pieces and store in an airtight container at room temperature. If desired, serve over your favorite ice cream.

Steps:

• For the cake:
• Preheat the oven to 350 degrees F.
• Butter and flour two 8-inch cake pans. Prepare the cake mix according to package instructions. Divide the batter between the 2 cake pans and bake according to package instructions. Remove from the oven and let cool on a wire rack.
• For the crunch:
• Place the toasted nuts close together in a single layer on a parchment-lined baking sheet. Combine the sugar and water in a small saucepan over medium-high heat. Stir the sugar mixture until dissolved. Bring to a boil and let cook until the sugar is light brown, about 8 minutes. Let the bubbles subside then pour the caramelized sugar over the nuts. Place the baking sheet in the refrigerator and let the sugar nut mixture cool until hard, about 30 minutes. When the sugar nut mixture is hard and cool, top with another piece of parchment paper and pound into small pieces, or place the sugar nut mixture on a cutting board and cut into small pieces. Set aside.
• For the filling:
• Put the mascarpone cheese, cream, powdered sugar, and vanilla into a large mixing bowl. Using an electric mixer whip the cream mixture to soft peaks. Fold the Crunch mixture into the whipped cream.
• For the topping:
• Place the chocolate, sugar and zest in a food processor. Process the mixture until the chocolate is finely ground.
• To assemble the cake:
• Put 1 cake on a serving plate. Top with 1-inch of the whipped cream crunch mixture. Top with the second layer of cake and continue frosting the entire cake with the remaining whipped cream crunch mixture. Sprinkle the top and sides of the cake with the ground chocolate. Serve.

Steps:

• Heat oil in a medium skillet over medium-high. Add rosemary and lemon zest and cook until fragrant, 30 seconds to 1 minute. Add hazelnuts and cook, stirring frequently, until nuts are golden brown and rosemary and lemon zest are crisp, 1 to 2 minutes more.
• Add sugar and lemon juice and continue cooking, stirring, until liquid darkens and nuts begin to caramelize, just a few seconds. Season with salt and pepper. Transfer to a bowl and let cool completely, about 30 minutes. Break apart into smaller pieces as desired. Crunch can be made ahead and stored in an airtight container at room temperature up to 2 days.

Steps:

• Line a 9 inch square pan with enough aluminum foil to extend a little past the edges, and butter the foil.
• Place chocolate chips in a glass bowl, and cook in the microwave, stirring every 20 to 30 seconds until melted and smooth. Spread the melted chocolate in the bottom of the prepared pan. Set aside in the refrigerator to cool while you make the candy part.
• In a small saucepan over medium heat, combine the sugar, butter, hazelnuts and corn syrup. Bring to a boil, stirring to blend as the butter melts. Heat the mixture to 250 to 265 degrees F (121 to 129 degrees C), or until a small amount of syrup dropped into cold water forms a rigid ball.
• Pour over the cooled chocolate, and spread into an even layer. Return to the refrigerator to cool. When completely cool, break into bite size pieces, and store in an airtight container.

Steps:

• For nut crunch:
• Line baking sheet with foil. Stir sugar and 1/4 cup water in heavy medium saucepan over medium-low heat until sugar dissolves. Increase heat; boil without stirring until syrup turns deep amber, brushing down sides with wet pastry brush and swirling pan occasionally. Mix in nuts. Pour onto foil; cool completely. Coarsely chop nut crunch. Set aside.
• For kumquats:
• Starting at rounded end, cut cross into each kumquat to within 1/4 inch of stem end. Bring wine, sugar, honey, and star anise to boil in heavy large saucepan, stirring until sugar dissolves. Scrape in seeds from vanilla bean; add bean. Add kumquats; simmer until almost tender, about 8 minutes. Using slotted spoon, transfer kumquats to plate; cool. Seed and finely chop enough kumquats to measure 2/3 cup (reserve remaining kumquats). Gently boil kumquat syrup until reduced to 11/4 cups, about 12 minutes. Cool.
• For cake:
• Preheat oven to 350°F. Line 15 1/2 x 10 1/2 x 1-inch or 17 x 11 x 3/4-inch baking sheet with foil; butter and flour foil. Finely grind nuts with flour in processor; transfer to medium bowl. Whisk in baking powder, spice, and salt. Using electric mixer, beat butter and sugar in large bowl until well blended. Beat in yolks and extracts. Beat in dry ingredients alternately with milk in several additions, just until combined. Using clean dry beaters, beat whites in another large bowl until stiff but not dry. Fold 1/3 of whites into batter to lighten, then fold in remaining whites. Spread batter evenly in prepared pan.
• Bake cake until tester inserted into center comes out clean, about 20 minutes for 17 x 11-inch cake and 28 minutes for 15 1/2 x 10 1/2-inch cake. Cool cake in pan on rack 20 minutes. Run knife around cake to loosen. Turn cake out onto foil-lined rack; cool completely. Cut hazelnut cake crosswise into 3 equal pieces.
• For frosting:
• Combine all ingredients in large bowl; beat to soft peaks (do not overbeat or mixture will curdle).
• Place 1 cake piece on platter. Spread 3/4 cup frosting over; sprinkle with 1/3 cup chopped kumquats and 1/3 cup nut crunch, then drizzle with 2 tablespoons kumquat syrup. Top with second cake piece. Spread 3/4 cup frosting over; sprinkle with 1/3 cup chopped kumquats and 1/3 cup nut crunch, then drizzle with 2 tablespoons kumquat syrup. Top with third cake piece. Spread remaining frosting over top and sides of cake. Drain remaining kumquats; remove seeds and any attached pulp. Top cake with kumquats, arranging like flowers. Do ahead Can be made 1 day ahead; cover and chill cake. Store remaining nut crunch and kumquat syrup at room temperature. Press remaining nut crunch around sides of cake. Drizzle 2 tablespoons syrup over cake and serve.

Steps:

• For cake:
• Position rack in bottom third of oven and preheat to 350°F. Line bottom of 9-inch-diameter cake pan with 2-inch-high sides with parchment paper. Melt butter in saucepan over medium heat. Remove from heat. Spoon off foam from top of butter and discard. Spoon clear yellow butter into small metal bowl, leaving water and milk solids in bottom of pan. Add vanilla to butter in bowl; set clarified butter aside.
• Sift flour and cocoa powder together 3 times into medium bowl. Whisk eggs and sugar in large metal bowl to blend. Place bowl with egg mixture in large skillet of barely simmering water; whisk constantly until egg mixture is lukewarm (105°F), about 2 minutes. Remove bowl from water. Place bowl with clarified butter in hot water in same skillet over low heat to keep warm.
• Using electric mixer, beat egg mixture until cool and tripled in volume, about 5 minutes. Sift 1/3 of flour-cocoa mixture over egg mixture and gently fold in with rubber spatula. Fold in remaining flour-cocoa mixture in 2 more additions. Fold 1 cup of cake batter into warm clarified butter until incorporated. Using rubber spatula, gently fold butter-cake batter mixture into remaining cake batter.
• Transfer batter to prepared pan. Bake until tester inserted into center of cake comes out clean and top springs back slightly when gently pressed, about 30 minutes. Cool completely in pan on rack. (Can be made 1 day ahead. Cover; store at room temperature.)
• Run knife between pan sides and cake to loosen. Invert cake onto rack; remove parchment. Using long serrated knife, trim top of cake horizontally, forming 3/4-inch-high cake layer. Using bottom of 8-inch-diameter springform pan as guide, trim around sides of cake to form 8-inch round cake. Set cake aside.
• For hazelnut crunch:
• Line bottom of 8-inch-diameter springform pan with parchment paper. Pour enough water into large skillet to reach depth of 1 inch; bring to simmer. Remove skillet from heat. Place gianduja in medium metal bowl; set bowl in hot water in skillet. Stir until gianduja is melted and smooth. Stir in cereal and nuts. Spread crunch evenly over parchment in pan. Place cake atop crunch layer, pressing to adhere. Chill until crunch is firm, about 1 hour.
• For mousse:
• Place gianduja in metal bowl. Pour enough water into large skillet to reach depth of 1 inch; bring to simmer. Remove from heat; place bowl with gianduja in hot water in skillet. Stir until gianduja is smooth. Remove bowl from water; cool gianduja to lukewarm.
• Using electric mixer, beat cream and salt in another bowl until very soft peaks form (when bowl is tilted, cream should be fluffy but still pourable and flow to one side). Mix 3 tablespoons water into melted gianduja. Pour whipped cream over and fold into gianduja just until incorporated (mousse will be very soft).
• Brush top of chilled cake with liqueur. Spread mousse over cake in pan. Cover and chill overnight. (Can be prepared 2 days ahead. Keep chilled.)
• Run knife between cake and pan sides to loosen. Soak kitchen towel in hot water; wring out water. Wrap hot wet towel around pan sides and hold 30 seconds. Carefully remove pan sides from cake; smooth mousse with knife if necessary. Place cake on pan bottom on rack set over baking sheet. Sift cocoa powder lightly over top of cake. Using stencils such as snowflakes or stars, sift powdered sugar over top of cake. Transfer to platter and serve.
• *Many supermarkets sell pre-husked hazelnuts. if you can't find them, here's how to husk whole hazelnuts: Scatter nuts on rimmed baking sheet and toast at 350°F until skins darken, 12 to 15 minutes. Wrap warm hazelnuts in kitchen towel and rub together to remove skins.
