Bûche De Noël With Marzipan Mushrooms 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

Steps:

• Mushrooms and buttercream:
• Preheat oven to 225°F. Whisk egg whites, sugar, cream of tartar, and salt in a large heatproof bowl set over a medium saucepan of simmering water (bowl should not touch water) until egg whites are very liquid (mixture will be warm to the touch) and sugar is dissolved (rub between your fingers to check), about 5 minutes. Remove bowl from heat and beat with an electric mixer until stiff, glossy peaks form (bowl will feel cool), about 5 minutes.
• Line a rimmed baking sheet with parchment paper and dust very lightly with cocoa powder. Scoop out 1 cup meringue. Dollop heaping teaspoonfuls of meringue onto prepared baking sheet, spacing at least 1 1/2" apart.
• Lightly dust meringue with more cocoa powder and place a sheet of parchment over top. Use an offset spatula or your hands to flatten meringue into irregularly shaped disks about 1/8" thick. Bake until lightly browned and parchment peels away easily, 75-90 minutes (meringue will be soft when it first comes out of the oven but will dry and crisp as it cools).
• Meanwhile, with mixer on medium speed, beat butter into remaining meringue, adding a piece at a time and waiting until incorporated before adding more. Beat until mixture is very smooth. (If it looks very loose or curdled, just keep beating; buttercream will come back together.) Add vanilla extract and scrape in vanilla seeds; beat to combine.
• Do Ahead
• Mushrooms and buttercream can be made 2 days ahead. Store mushrooms airtight at room temperature. Cover and chill buttercream; bring to room temperature, then beat until smooth before using.
• Sponge Cake:
• Increase oven to 400°F. Coat a 26x18" rimmed baking sheet with nonstick spray and line with parchment paper, leaving overhang on long sides. Spray parchment. Whisk flour, cornstarch, and ⅓ cup cocoa powder in a small bowl.
• Bring milk, butter, oil, vanilla, and salt to a simmer in a small saucepan over medium-low heat. Keep warm over low heat.
• Meanwhile, beat eggs and egg yolks with an electric mixer on medium speed until smooth. Increase speed to high; beat until doubled in volume. With motor running, gradually add sugar; beat until very light and fluffy and mixture falls back on itself in a slowly dissolving ribbon (it should be at least quadrupled in volume), about 5 minutes.
• Reduce speed to medium and gradually stream in milk mixture. Sift one-third of dry ingredients over top; gently fold in until only a few streaks remain. Working in 2 additions, repeat with remaining dry ingredients, scraping bottom of bowl and using as few strokes as possible to keep eggs from deflating (a few streaks are fine). Scrape batter into prepared baking sheet and gently spread to edges of pan. Tap sheet lightly on counter to pop any large air bubbles.
• Bake cake until surface is puffed and springy to the touch, 10-12 minutes.
• Let cake cool in pan 2 minutes, then run a knife along short edges to loosen. Invert onto a wire rack and carefully peel away parchment. Using a fine-mesh sieve, dust cake with cocoa powder. Cover with a large kitchen towel. Place another wire rack on top and flip cake over so towel side is underneath. Remove top rack; dust exposed side with cocoa powder. Starting at one of the long sides, gently roll up warm cake inside towel. Let cake cool, seam side down, 30-35 minutes.
• Do Ahead
• Cake can be baked 1 day ahead. Store tightly wrapped in plastic at room temperature.
• Assembly:
• Carefully unroll towel and cake on a flat surface (cake will curl at the ends and may have a few small cracks but should stay in 1 piece). Position cake so the end that was in innermost part of spiral is closest to you; brush off any excess cocoa.
• Using a pastry brush, gently dab cocoa syrup over entire surface of cake; you may not use it all. Dollop bittersweet ganache over top and smooth with an offset spatula to create an even layer.
• Dollop mascarpone filling over ganache; carefully spread over surface, trying not to blend with ganache and avoiding last inch of cake along long side farthest from you.
• Using towel to lift edge nearest you, reroll cake, keeping towel on exterior. Chill, seam side down, until filling is set, about 30 minutes.
• Transfer filled cake to a baking sheet. Set aside 1/2 cup buttercream for attaching branches. Evenly spread remaining buttercream over cake with an offset spatula.
• Using a long serrated knife, trim 1/2" of cake from each end to create clean edges; discard (or eat!). Slice off a 4" piece of cake. Starting 1" from end, divide 4" piece in half, cutting at a 45° angle, leaving 1" at opposite end. Transfer log to a platter.
• Place angled side of each small piece of cake against roll to create branches, positioning one on top and the other on the side using a large dab of buttercream to secure. Cover any exposed cake on sides with more buttercream but leave cut ends exposed.
• Use spatula to create textured lines in buttercream to look like birch bark.
• Knead together marzipan and cocoa powder on a surface until smooth. Roll out on a sheet of parchment paper to less than 1/8" thick, then cut out wavy strips to look like tree knots; drape over buttercream and press gently to adhere.
• Using either a pastry bag fitted with a very small round tip or a disposable plastic bag with one corner snipped off, drizzle melted chocolate over log to mimic birch bark striations. Chill Bûche de Noël, uncovered, until ready to serve.
• Just before serving, press mushrooms perpendicularly into log in groups of 2 or 3.
• Do Ahead
• Bûche de Noël (without meringue mushrooms) can be assembled 1 day ahead. Wrap in plastic and chill. Attach mushrooms just before serving.

BûCHE DE NOëL WITH MARZIPAN MUSHROOMS

Steps:

• For filling:
• Bring milk to boil in medium saucepan over medium heat. Whisk yolks and sugar in small bowl until well blended; whisk in flour. Whisk hot milk into egg mixture. Return to same saucepan. Whisk over medium heat until custard thickens and boils, about 1 1/2 minutes. Transfer to processor; cool to room temperature, about 1 hour. Add marzipan; process until smooth, about 1 minute. Blend in butter 1 piece at a time, then both extracts. Cover and refrigerate filling at least 4 hours or up to 2 days.
• For cake:
• Preheat oven to 350°F. Butter 11x10x1-inch jelly roll pan. Line bottom with parchment paper; butter and flour parchment. Whisk eggs, 3/4 cup sugar, vanilla and salt in large metal bowl. Set bowl over pot of simmering water. Whisk until just warm, about 2 minutes. Remove bowl from over water. Using electric mixer, beat mixture until tripled in volume, about 6 minutes. Sift flour over; fold in until just combined. Gently fold in butter (do not overmix, or batter will deflate). Spread batter in prepared pan. Bake until tester inserted into center comes out clean, about 20 minutes. Sift powdered sugar over towel. Run knife around edge of pan to loosen cake. Turn hot cake out onto towel. Peel off parchment. Starting at 1 long side and using towel as aid, gently roll up cake jelly-roll style. Cool. Unroll cake. Spread filling over. Reroll cake; place cake, seam side down, on platter. Refrigerate cake while preparing frosting.
• For frosting:
• Bring cream and butter to boil in medium saucepan over medium-high heat, stirring to melt butter. Remove from heat. Add both chocolates; whisk until melted. Transfer to medium bowl. Let cool at room temperature until thick enough to spread, about 1 hour.
• Starting 1 inch in from each end of cake, cut on diagonal to remove one 3-inch-long piece of cake from each end. Attach 1 cake piece at sides of cake near each end. Spread frosting over top and sides of cake and pieces. Using tines of fork, draw concentric circles on cake ends to resemble tree rings. Draw fork along length of cake to form bark design. Garnish with Marzipan Mushrooms.
