Best Meringue Mushrooms For Birch De Noel Recipes

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.

MERINGUE MUSHROOMS RECIPE

Steps:

• Add 2 egg whites, 1/2 cup sugar, 1/8 tsp salt and 1/8 tsp cream of tartar and beat with whisk attachment on high speed 7 min or until you have glossy ribbons and the peaks stay fairly stiff.
• Transfer meringue to your pastry bag fitted with a 3/8" round tip and pipe onto lined cookie sheet (about 1″ apart). Mushroom caps should look like large chocolate kisses (1 1/2" diameter at the base) with the tip swirled into the side so you get an even top. If you're a perfectionist; you can smooth the mushroom caps with a wet fingertip. Mushroom stems should look like slimmer/taller kisses (3/4" diameter at the base) and tips pointed up.
• Bake at 200˚F for 1 hour 30 min. They should slide easily off the parchment paper easily when they are done. Remove from oven and pull parchment paper off the baking sheet. Let cool on paper completely to room temp. Note: When they come out of the oven, they will be crisp on the outside and a little marshmallowy on the inside, but will harden as they cool.
• To assemble, dust the tops and stems lightly with cocoa powder. If you like, you can smudge the cocoa powder with your fingers to give them that natural dirty glow :). Rotate the tip of a small paring knife in the center of each mushroom cap to cut a small hole just large enough to fit the tip of the base.
• Now melt chocolate, transfer into a ziploc bag, snip off a tiny hole from the corner of the bag and pipe chocolate into the holes of meringue. Stick the bases into the holes and leave them upside-down until chocolate hardens and sets. Gently transfer set cookies to an airtight container and store for several days at room temp. Do not refrigerate.

BIRCH DE NOEL

Steps:

• Preheat oven to 350°F. Test each of the three eyes at stem end of coconut to find softest one. Use an ice pick and a hammer to pierce it, then drain the juice into a glass through a fine sieve and reserve for another use. Tap coconut with hammer until a palm-size piece of shell breaks off. Continue tapping around broken edge until shell begins to break apart. Place broken shell on a baking sheet; bake about 10 min- utes to loosen flesh. Remove from oven and let cool slightly. Pry out flesh with a paring knife. With a potato peeler, remove any remaining brown skin from flesh.
• Reduce oven temperature to 250°. Using a vegetable peeler, shave largest pieces of coconut into long curls, place on baking sheet, and bake until just dry but no color has developed, 15 to 20 minutes. Meanwhile, grate smaller coconut pieces on the small holes of a box grater. (You will need about 1/2 cup grated coconut for the filling.)
• Increase oven temperature to 400°. Coat a 12 1/2-by-17 1/2-inch rimmed baking sheet with cooking spray. Line with parchment paper; coat with cooking spray. Dust with cocoa; tap out excess. Whisk together cocoa powder, flour, and salt in a bowl. In a heat-proof mixer bowl set over (not in) a pan of simmering water, whisk together eggs, yolks, and granulated sugar until sugar has dissolved and mixture is warm to the touch. Attach bowl to mixer fitted with the whisk attachment and beat on medium-high speed 2 minutes. Raise speed to high; beat until mixture is pale and thick, about 4 minutes more.
• Sift cocoa mixture over egg mixture; carefully fold in with a large rubber spatula. When almost incorporated, pour melted butter down side of bowl; gently fold to combine. Pour batter into prepared sheet, and smooth top with an offset spatula.
• Bake until cake springs back when touched, 9 to 10 minutes. Place a clean kitchen towel on a work surface; dust generously with cocoa. Remove pan from oven and immediately turn cake out onto a wire rack lined with parchment. Invert onto prepared towel; remove parchment.
• While cake is still warm, gently roll, starting from one short side, into a log, incorporating towel. Let rolled cake cool completely. (This will give it a "shape memory," so it will be easier to roll again with filling.)
• Unroll cooled cake and transfer to parchment. Using a pastry brush, coat cake with rum. Using offset spatula, spread mousse over cake. Sprinkle with 1/2 cup reserved grated coconut.
• With a short end of cake facing you, roll carefully into a roulade. Wrap in a kitchen towel; secure with clothespins or large metal binder clips to hold roll in a tight round shape. Place on a baking sheet and refrigerate until firm, at least 2 hours and up to 1 day.
• Remove from refrigerator and unwrap. Use a serrated knife to trim ends of roll, cutting on the bias (starting 1 inch in from end on shorter side, and finishing 2 inches in, to create a wedge). Choose the more presentable trimmed end and place, cut-side up, on log, forming a branch. If desired, use other trimmed end for a second branch.
• Transfer log to a serving platter. Slide strips of parchment under perimeter of log (to keep platter clean). Use offset spatula to coat log with frosting, then attach one or both trimmed ends; coat with frosting. Remove parchment pieces. Decorate with meringue mushrooms, coconut shavings, and rosemary sprigs.

MERINGUE MUSHROOMS

Steps:

• Heat oven to 225 degrees. Line a baking sheet with parchment paper, and set aside.
• In a small saucepan, heat sugar and 1/2 cup water over low heat until sugar dissolves. Bring to a boil; cook until liquid reaches 248 degrees (hard-ball stage) on a candy thermometer.
• Meanwhile, in the bowl of an electric beater fitted with the whisk attachment, whip egg whites on low speed until soft peaks form. Increase speed to high, and add hot syrup in a steady stream, beating constantly. Continue beating until cool and stiff, about 5 minutes. Beat in vanilla. Fold in cocoa powder.
• Spoon meringue into a large pastry bag fitted with a coupler and large plain tip. Pipe meringue onto prepared baking sheet to form 2-inch domes. Pipe a separate stem shape for each dome.
• Sprinkle cocoa powder lightly over meringues. Bake until dry, about 2 hours. Store in an airtight container until ready to use.
• To assemble mushrooms, melt chocolate in a double boiler or in a heat-proof bowl set over a pan of simmering water. Trim off points from tops of stems. With a small offset spatula, spread chocolate on underside of a cap and place trimmed end of stem into center of cap. Place mushroom, stem side up, in an egg carton to harden. Repeat with remaining mushrooms; refrigerate until set.

MERINGUE MUSHROOMS FOR BIRCH DE NOEL

Steps:

• Heat oven to 200 degrees. Place Swiss meringue in an 18-inch pastry bag fitted with a large 3/4-inch round tip. Line two baking sheets with parchment paper. Pipe meringue, forming domes 1 to 2 inches in diameter. Pipe a stem shape for each dome. Bake for 1 hour; reduce heat to 175 degrees, and continue baking until meringues are completely dry to the touch but not browned, 45 to 60 minutes more.
• Fill a medium saucepan one-quarter full with water. Set over medium heat, and bring to a simmer. Place bittersweet chocolate in a heat-proof bowl, and set over simmering water. Turn off heat; stir chocolate occasionally until completely melted. Using an offset spatula, spread bottoms of domed meringues with chocolate; let sit at room temperature.
• Place white chocolate in a heat-proof bowl, and set over simmering water. Turn off heat; stir chocolate occasionally until completely melted. Allow to cool slightly. To create mushroom gills, spread white chocolate over dark chocolate; use a toothpick to create lines from the center of the cap's underside to the edges. Let set in a cool, dry place.
• Poke a small hole in the center of each mushroom cap using a paring knife. Dip the pointed end of each of the mushroom stems in melted white chocolate, and insert into hole in center of cap. Allow to set. Meringue mushrooms should be kept in an airtight container in a cool, dry place.

MERINGUE MUSHROOMS

Steps:

• Preheat the oven to 225 degrees F (110 degrees C). Line 2 cookie sheets with parchment paper or aluminum foil.
• In a large glass or metal bowl, use an electric mixer to whip egg whites until foamy. Add cream of tartar, salt, and vanilla. Continue whipping until the whites hold soft peaks. Gradually sprinkle in the sugar so that it does not sink to the bottom, and continue whipping until the mixture holds stiff shiny peaks.
• Place a round tip into a pastry bag, and fill the bag half way with the meringue. To pipe the mushroom caps, squeeze out round mounds of meringue onto one of the prepared cookie sheets. Pull the bag off to the side to avoid making peaks on the top. For the stems, press out a tiny bit of meringue onto the other sheet, then pull the bag straight up. They should resemble candy kisses. Do not worry about making all of the pieces exactly the same. The mushrooms will look more natural if the pieces are different sizes. Dust the mushroom caps lightly with cocoa using a small sifter or strainer.
• Bake for 1 hour in the preheated oven, or until the caps are dry enough to easily remove from the cookie sheets. Set aside to cool completely. Melt the coating chocolate in a metal bowl over simmering water, or in a glass bowl in the microwave, stirring occasionally until smooth.
• Poke a small hole in the bottom of a mushroom cap. Spread chocolate over the bottom of the cap. Dip the tip of a stem in chocolate, and press lightly into the hole. When the chocolate sets, they will hold together. Repeat with remaining pieces. Store at room temperature in a dry place or tin.

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.

MERINGUE MUSHROOMS

Steps:

• Heat oven to 200 degrees. Place Swiss Meringue in an 18-inch pastry bag fitted with a large round tip (Wilton #1A). Line two baking sheets with parchment. Pipe meringue, forming domes 1 to 2 inches in diameter. Pipe a stem shape for each dome. Place baking sheets in oven for 1 hour, reduce heat to 175 degrees, and continue baking until meringues are completely dry to the touch but not browned, 45 to 60 minutes.
• Fill a medium saucepan one quarter full with water. Set over medium heat, and bring water to a simmer. Place bittersweet chocolate in a heat-proof bowl, and set over simmering water. Turn off heat; stir occasionally until completely melted. Using an offset spatula, spread bottoms of domed meringues with chocolate; let set at room temperature.
• Place white chocolate in a heat-proof bowl, and set over simmering water. Turn off heat; stir occasionally until completely melted. Allow to cool slightly. Spread white chocolate over dark chocolate; use a toothpick to create lines from the center of the cap to the edges. Let set in a cool, dry place.
• Poke a small hole in the center of each mushroom cap using a paring knife. Dip the pointed end of each of the mushroom stems in melted white chocolate, and insert into hole in center of cap. Allow to set. Meringue mushrooms should be kept in an airtight container in a cool, dry place.
