Chocolate Hazelnut Semifreddo Recipe By Giada

CITRUS SEMIFREDDO

Steps:

• Spray a 9 by 5 by 3-inch metal loaf pan with nonstick spray. Line the pan with plastic wrap, allowing the excess to hang over the ends and sides.
• Combine the crushed amaretti cookies and the melted butter. Put in the lined pan and press down to firm and form a crust.
• Whisk 1/2 cup of the sugar, the egg yolks, lemon juice, lime juice, limoncello, and salt in a large metal bowl to blend. Set the bowl over a saucepan of simmering water (do not allow the bottom of the bowl to touch the water). Whisk the egg mixture until it is thick and creamy, and a thermometer inserted into the mixture registers 160 degrees F, about 5 minutes. Set the bowl of custard into another bowl of ice water to cool completely. Stir in the zest.
• Using an electric mixer, beat the cream and remaining 1/4 cup sugar in another large bowl until firm peaks form. Using a large rubber spatula, gently fold the whipped cream into the custard. Spoon the mixture onto the prepared crust. Fold the overhanging plastic wrap over the custard and freeze until frozen, at least 8 hours or up to 3 days.
• Unfold the plastic wrap. Invert the semifreddo onto a platter and peel off the plastic wrap. Cut the semifreddo into 1-inch slices and sprinkle with crushed amaretti cookies and serve.

CHOCOLATE HAZELNUT SEMIFREDDO

Steps:

• Special equipment: 3 by 15-inch piece of parchment paper, a 7 1/2 by 12-inch piece of parchment paper.
• For the crust: Put an oven rack in the center of the oven. Preheat the oven to 350 degrees F. Spray a 9 by 5 by 3-inch nonstick loaf pan with vegetable oil cooking spray. Using 2 pieces of parchment paper, line the pan, allowing the excess to hang over the ends and sides.
• In a food processor, blend the biscotti and hazelnuts together until finely ground. Add the melted butter and pulse until the crumbs are moistened. Using a flexible spatula, press the crumb mixture into the bottom of the prepared pan. Bake for 8 to 10 minutes until the edges of the crust are golden. Cool the pan on a wire rack for 20 minutes.
• For the filling: In a medium stainless steel or glass bowl, whisk together the egg yolks, 1/2 cup sugar, vanilla extract, and salt until smooth. Put the bowl over a pan of simmering water, making sure the bottom of the bowl does not touch the water. Whisk until the egg mixture is pale, thick and creamy, and an instant-read thermometer registers 160 degrees F, about 10 to 15 minutes. Put the bowl into a larger bowl of iced water to cool completely.
• In another medium bowl, using an electric mixer, beat the cream until thick. Add the remaining 1/4 cup sugar and beat until the cream holds stiff peaks. Mix 1/4 of the cream into the cooled custard. Using a spatula, gently fold the remaining cream into the custard. Drop spoonfuls of the chocolate-hazelnut spread over the custard mixture and gently fold until just incorporated but still chunky. Spoon the mixture onto the prepared crust. Fold the overhanging parchment paper over the custard and freeze for at least 8 hours or up to 3 days.
• Run a thin-bladed spatula around the semifreddo between the parchment paper and the pan. Unfold the parchment paper and invert the semifreddo onto a platter. Peel off the paper and cut into 1-inch thick slices. Serve on chilled plates.
• Cook's Note: to toast the hazelnuts, arrange in a single layer on a baking sheet. Bake in a preheated 350 degrees F oven for 8 to 10 minutes until lightly toasted. Cool completely before using.

HAZELNUT SEMIFREDDO

Steps:

• Grease a 10-inch spring form pan and line with parchment paper.
• In a food processor grind the hazelnuts and 3/4 cup sugar together, pulsing to avoid over blending so it does not become a paste. Whip the cream using a mixer fitted with a whisk attachment or a hand mixer, until fluffy, soft peaks. Transfer to the refrigerator.
• In a clean dry bowl, whip the egg whites until soft peaks form. Add the vanilla extract and 1/4 cup sugar and continue whipping until glossy and stiff, about 30 seconds more. Fold into the whipped cream, then fold in the ground nut mixture. Spoon the mixture into the spring form pan. Smooth the top. Freeze at least 4 hours or overnight.
• Warm Glossy Chocolate Sauce: In the top half of a double boiler, combine the 2 chocolates over simmering water. Stir constantly until melted, then whisk in the corn syrup and water. Whisk until smooth and shiny.
• When ready to eat, remove the collar and serve frozen with chocolate sauce.
• *RAW EGG WARNING
• Food Network Kitchens suggest caution in consuming raw and lightly-cooked eggs due to the slight risk of Salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly-refrigerated, clean, grade A or AA eggs with intact shells, and avoid contact between the yolks or whites and the shell.

CHOCOLATE AND HAZELNUT SEMIFREDDO

Steps:

• Double line a 900g/2lb loaf tin with cling film.
• For the ganache, melt the chocolate and butter in a large heatproof bowl over a saucepan of simmering water (do not allow the bottom of the bowl to touch the water). Stir in the icing sugar and double cream. Set aside.
• Meanwhile, place the egg, egg yolks, vanilla extract and sugar in a heatproof bowl and set it over a saucepan of simmering water, making sure the bowl doesn't touch the water. Beat the mixture over the heat for about 8 minutes using a hand-held electric whisk, until it is thick and pale. Remove from the heat and set aside.
• In a separate large bowl, whip the double cream until it is just stiff. Gently fold in the pale egg mixture until combined.
• Pour half the mix into the prepared loaf tin. Make a shallow well along the centre and pour in the ganache. Pour the rest of the semifreddo mix over the top and use a knife to make swirls with the ganache. Cover with cling film and place in the freezer to set for 6 hours.
• Just before serving, melt the chocolate pieces in a bowl standing over a pan of simmering water (do not allow the bottom of the bowl to touch the water). Set aside to cool to room temperature.
• To serve, turn the semifreddo out onto a serving platter and carefully remove the cling film. Pour the cooled chocolate over the top, sprinkle with the toasted hazelnuts and serve in generous slices.
