Grapefruit Almond Gin And Labne Buche De Noel Recipes

BUCHE DE NOEL

Steps:

• To make the buttercream: Whisk the egg whites and sugar together in the bowl of an electric mixer. Set the bowl over simmering water and whisk gently until the sugar is dissolved and the egg whites are hot. Attach the bowl to the mixer and whip with the whisk on medium speed until cooled. Switch to the paddle and beat in the softened butter and continue beating until the buttercream is smooth. Dissolve the instant coffee in the liquor and beat into the buttercream.
• Turn the genoise layer over and peel away the paper. Invert onto a fresh piece of paper. Spread the layer with half the buttercream. Use the paper to help you roll the cake into a tight cylinder Transfer to baking sheet and refrigerate for at least 30 minutes or until set. Reserve the remaining buttercream for the outside of the buche.
• To make the marzipan: Combine the almond paste and 1 cup of the sugar in the bowl of the electric mixer and beat with the paddle attachment on low speed until the sugar is almost absorbed. Add the remaining 1 cup sugar and mix until the mixture resembles fine crumbs. Add half the corn syrup, then continue mixing until a bit of the marzipan holds together when squeezed, adding additional corn syrup a little at a time, as necessary; the marzipan in the bowl will still appear crumbly. Transfer the marzipan to a work surface and knead until smooth.
• To make marzipan mushrooms: Roll 1/3 of the marzipan into a 6-inch long cylinder and cut into 1-inch lengths. Roll half the lengths into balls. Press the remaining cylindrical lengths (stems) into the balls (caps) to make mushrooms. Smudge with cocoa powder. To make holly leaves: Knead green color into 1/2 the remaining marzipan and roll it into a long cylinder. Flatten with the back of a spoon, then loosen it from the surface with a spatula. Cut into diamonds to make leaves, or use a cutter.
• To make holly berries: Knead red color into a tiny piece of marzipan. Roll into tiny balls.
• To make pine cones, knead cocoa powder into the remaining marzipan. Divide in half and form into 2 cone shapes. Slash the sides of cones with the points of a pair of scissors.
• Unwrap the cake. Trim the ends on the diagonal, starting the cuts about 2 inches away from each end. Position the larger cut piece on the buche about 2/3 across the top. Cover the buche with the reserved buttercream, making sure to curve around the protruding stump. Streak the buttercream with a fork or decorating comb to resemble bark. Transfer the buche to a platter and decorate with the marzipan. Sprinkle the platter and buche sparingly with confectioners' sugar "snow."
• Storage: Keep at cool room temperature. Cover leftovers loosely and keep at room temperature.
• Set rack in the middle of the oven and preheat to 400 degrees.
• Half-fill a medium saucepan with water and bring it to a boil over high heat. Lower the heat so the water is simmering.
• Whisk the eggs, yolks, salt, and sugar together in the bowl of a heavy-duty mixer. Place over the pan of simmering water and whisk gently until the mixture is just lukewarm, about 100 degrees (test with your finger). Attach the bowl to the mixer and with the whisk attachment, whip on medium-high speed until the egg mixture is cooled (touch the outside of the bowl to tell) and tripled in volume.
• While the eggs are whipping, stir together the flour, cornstarch, and cocoa.
• Sift 1/3 of the flour mixture over the beaten eggs. Use a rubber spatula to fold in the flour mixture, making sure to scrape all the way to the bottom of the bowl on every pass through the batter to prevent the flour mixture from accumulating there and making lumps. Repeat with another 1/3 of the flour mixture and finally with the remainder.
• Scrape the batter into the prepared pan and smooth the top. Bake the genoise for about 10 to 12 minutes, or until well risen, deep and firm to the touch. (Make sure the cake doesn't overbake and become too dry, or it will be hard to roll.)
• Use a small paring knife to loosen the cake from the sides of the pan. Invert the cake onto a rack and let the cake cool right side up on the paper. Remove the paper when the cake is cool.
• Storage: Wrap in plastic wrap and refrigerate for several days, or double-wrap and freeze for up to a month.

BûCHE DE NOëL (YULE LOG)

Steps:

• If you want to decorate the cake with sugared cranberries and rosemary, start them the night before because they need to sit for several hours. Place cranberries and rosemary in a large bowl; set aside. In a medium saucepan, bring 1 cup of sugar and the water to a boil and whisk until the sugar has dissolved. Remove pan from the heat and allow to cool for 5 minutes. Pour sugar syrup over the cranberries and rosemary and stir to combine. Let the cranberries and rosemary sit at room temperature or in the refrigerator (lightly covered) for 6 hours or overnight. You'll notice the sugar syrup is quite thick after this amount of time. Drain the cranberries and rosemary from the syrup and pour 1 cup of sugar on top. Toss to coat. Pour the sugared cranberries and rosemary on a parchment paper or silicone baking mat-lined baking sheet and let them dry for at least 2 hours at room temperature or in the refrigerator.
• Preheat oven to 350°F (177°C). Spray a 12×17 inch baking pan with nonstick spray or grease with butter, so the parchment paper sticks. Then line it with parchment paper so the cake seamlessly releases. Spray or grease the parchment paper too. We want an extremely nonstick surface for this cake roll.
• Whisk the cake flour, cocoa powder, baking powder, and salt together in a medium bowl. Set aside until the next step. Using a hand mixer or a stand mixer fitted with whisk attachment, beat the egg whites and 1/2 cup (100g) sugar together on high speed for 4-5 minutes or until stiff peaks form. Transfer to another bowl. Using the same mixing bowl you just had the egg whites in (no need to clean it), add the egg yolks, remaining sugar, oil, and vanilla extract. Beat together on high speed for 3-4 minutes or until thickened and light in color.
• Add half of the whipped egg whites into the egg yolk mixture. Beat on low speed for 10 seconds. Repeat with remaining egg whites and beat on low for 10 seconds. Add half of the flour mixture and beat on low or fold with a rubber spatula until combined. Repeat with remaining flour mixture. Avoid over-mixing and deflating those egg whites. Batter will be very light.
• Spread batter evenly into prepared pan. Gently bang the pan on the counter a couple times to pop any air bubbles. Bake for 18-19 minutes or until the cake springs back when lightly poked with your finger. Cake will look a little bubbly on top when it's done. That's ok. Avoid over-baking cake because it will crack if over-baked. As the cake bakes, get started on the next step.
• As the cake bakes, place a piece of parchment paper (larger than the cake) or a thin kitchen/tea towel flat on the counter. (Note: I find a kitchen towel is better to help prevent cracking.) Using a fine mesh sieve, dust parchment/towel with 3 Tablespoons (15g) of cocoa powder. Once the cake comes out of the oven, quickly run a knife around the edges to loosen it. Immediately invert it onto the parchment/towel. Peel off the parchment paper that was on the bottom of the cake as it baked. Starting with the narrow end, begin tightly rolling the hot cake up with the parchment/towel. Do this slowly and gently. The cake will be warm. Allow the cake to cool completely rolled up in the parchment/towel. Feel free to place it in the refrigerator to speed it up, about 3 hours and up to 1 day.
• Preheat oven to 200°F (93°C). Line a large baking sheet with parchment paper or a silicone baking mat. In a completely clean residue-free large glass or metal mixing bowl, using a handheld mixer or stand mixer fitted with a whisk attachment, beat the egg white, cream of tartar, and salt together on high speed until foamy, about 2 minutes- this is a small amount and the whisk on a stand mixer might not reach it, so whisk by hand until foamy if needed. With the mixer running on high speed, slowly add the sugar and beat until stiff glossy peaks form, about 2 more minutes. Snip off the end of a plastic bag or fit a round piping tip in a piping bag. I use and recommend Wilton 2A piping tip or any tip with around a 1/2 inch opening. Pipe quarter-sized circles (these will be the round mushroom tops) and 1-inch tall cones (these will be the stems). You will have enough meringue batter for about 16 mushrooms. I usually only make 8-12 and discard leftovers, but feel free to make all 16. Using a moistened finger (just a dab of water is fine), smooth down any peaks. If desired, lightly dust mushroom tops with cocoa powder using a fine mesh sieve. Bake for 2 hours. Do not open the oven as the meringues bake. Turn off the oven after 2 hours and let the meringues sit inside the cooling oven for 20 minutes. Remove meringues from the oven and cool completely. When they're just about cool, melt the 1 ounce of chocolate in a double boiler or use the microwave. If using the microwave, melt in 15 second increments, stopping and stirring between each until melted and smooth. Cool for 5-10 minutes. (Easier to adhere mushrooms if the melted chocolate is a bit cool.) Once meringues have cooled, use a flat spatula to remove them from the baking sheets. Dot a bit of chocolate onto the center of the bottom of a mushroom top. Adhere a mushroom stem to it. Place back on the baking sheet to set. If stems or tops still have a little peak, scrape off with a knife or your spatula, as you see me do in the video above. Leaning them against the rim is helpful if they keep toppling over. Repeat with remaining tops and stems to form mushrooms. Let chocolate cool and harden, about 1 hour.
• Remove the cake roll from the refrigerator and allow to sit on the counter for a few minutes to warm up as you prepare the whipped cream.
• Using a hand mixer or a stand mixer fitted with a whisk attachment, whip the heavy cream, Frangelico, confectioners' sugar, and cocoa powder on medium-high speed until medium to stiff peaks form, about 2-3 minutes.
• Gently and very slowly unroll the cake. Spread whipped cream evenly on top, leaving about a 1/2 inch border around the cake. I like using a large or small offset spatula to spread. Sprinkle chopped hazelnuts on top. Gently roll the cake back up, without the parchment/towel this time. Roll it slowly. This part is messy. Carefully place on a cutting board. If the exterior of the cake looks moist, dust with a little cocoa powder. Cover with plastic wrap and refrigerate for at least 30 minutes and up to 2 days before shaping and topping with ganache.
• Place chopped chocolate in a medium bowl. Heat the cream in a small saucepan until it begins to simmer. (Do not let it come to a rapid boil- that's too hot.) Pour over chocolate, then let it sit for 2-3 minutes to gently soften the chocolate. Slowly stir until completely combined and chocolate has melted. Ganache will be thin, so it has to thicken before using. Refrigerate, uncovered, for at least 30 minutes and up to 1 hour to thicken.
• Remove rolled cake from the refrigerator. Diagonally slice a 3-4 inch section off one end. At this point, I usually place the cake on a serving platter. Place the angled side against a side of the roll, forming a branch. Slowly pour and spread thickened ganache all over the top and sides of cake. Feel free to leave the cut ends exposed (as you see in these photos) or spread ganache over the ends- there should be plenty of ganache to use. Use a fork to make textured lines resembling tree bark. Feel free to wipe the serving plate if ganache dripped all over.
• Decorate with meringue mushrooms, sugared cranberries and rosemary, and a dusting of confectioners' sugar just before serving.
• Cover leftover cake and store in the refrigerator for up to 3 days.

BûCHE DE NOëL (A FRENCH CHRISTMAS DESSERT) RECIPE BY TASTY

Steps:

• Make the chocolate sponge cake: Preheat the oven to 350°F (180°C). Grease a roll cake baking pan or 18 x 13-inch (45 x 33 cm) baking sheet with nonstick spray and line with parchment paper.
• In a large bowl, whisk together the egg yolks and 3 tablespoons of sugar until the sugar is dissolved.
• Whisk in the milk, vegetable oil, and vanilla until smooth. Sift in the flour, cocoa powder, and cornstarch and whisk until smooth.
• In a large bowl with an electric hand mixer, or the bowl of a stand mixer fitted with the whisk attachment, whip the egg whites on medium speed until frothy, about 2 minutes. Add the cream of tartar and whip on medium-low speed for 2 minutes, then gradually add the remaining ½ cup (100 G) superfine sugar. Whip on medium-high speed until stiff peaks form, another 2-3 minutes.
• Fold the egg white mixture into the egg yolk mixture until just combined, taking care not to overmix.
• Spread the batter evenly on the prepared pan. Bake for 12-15 minutes, until fluffy and the cake springs back when gently pressed.
• Drape a kitchen towel over the cake and set a wire rack on top. Carefully invert the cake onto the rack, peel back the parchment from the bottom, and let cool for 10 minutes. Carefully roll the cake into a log with the towel inside and allow to cool completely.
• While the cake cools, make the chocolate hazelnut buttercream: In a large bowl, beat the butter and powdered sugar with an electric hand mixer on low speed until combined. Increase the speed to high and whip for 2-3 minutes, until light and fluffy.
• Reduce the speed to low and add the milk, vanilla, and salt. Whip again for 2-3 minutes until well incorporated and the buttercream is light, bright white, and fluffy.
• Fold in the chocolate-hazelnut spread with a rubber spatula. Cover with a kitchen towel or place wrap and set aside at room temperature.
• Make the ganache: Place the chopped chocolate in a medium bowl. Pour the hot cream over the chocolate. Stir until the chocolate is melted. Refrigerate the ganache for at least 30 minutes to firm.
• Make the meringue mushrooms: Reduce the oven temperature to 200°F (93°C). Line a baking sheet with parchment paper.
• In a medium bowl, beat the egg whites and cream of tartar with an electric hand mixer until soft peaks form, about 3 minutes.
• Gradually add the sugar and whip until dissolved and stiff peaks form, about 2 minutes more. The mixture should be glossy, shiny, and very stiff.
• Transfer the mixture to a piping bag fitted with a medium round tip. Pipe half of the meringue onto the prepared baking sheet in ½-1 inch (2.54 cm) wide circles resembling mushroom caps. Use your fingers to gently press down any peaks. Pipe the remaining meringue into ½-1 inch (2.54 cm) long stems. Dust the mushrooms with cocoa powder.
• Bake for 1½-2 hours, until the mushrooms are completely dried and hard to the touch. Turn off the oven and leave the mushrooms dry out in the oven for at least 30 minutes, or up to overnight. The mushrooms can be made 1-2 days ahead.
• Assemble the mushrooms: Dip the flat sides of the mushroom caps in the melted chocolate and attach the mushroom stems. Stand the mushrooms upright and let dry, 30-45 minutes.
• Make the sugared cranberries and rosemary: Line a baking sheet with parchment paper and top with a wire rack.
• In a small saucepan, combine 1 cup (200 G) sugar and the water. Bring to a boil, whisking to dissolve the sugar. Drop the cranberries into the syrup and stir to coat, then remove with a slotted spoon and transfer to one side of the wire rack. Let cool for at least 1 hour, until no longer sticky, then sprinkle cranberries with ¼ cup (25 G) sugar. Set aside.
• Bring the remaining syrup to a boil. Add the rosemary sprigs and stir to coat, then remove with a slotted spoon and transfer to the other side of the wire rack. Let cool for at least 1 hour, then sprinkle rosemary with the remaining ¼ cup (25 G) sugar. Set aside.
• Assemble the bûche de noël: Unroll the sponge cake.
• Spread 2 cups (230 G) of the chocolate-hazelnut buttercream. evenly over the cake, leaving a 1-inch (2.54 cm) border around all sides.
