Spring Croquembouche Recipes

CROQUEMBOUCHE

Steps:

• For the croquembouche: Place a rack in the middle of the oven and preheat to 400 degrees F. Line a baking sheet with parchment paper.
• In a medium saucepan, combine the butter, sugar, salt and 1 cup water. Bring to a boil over medium heat. Remove from the heat and dump the flour directly into the pan. Stir the mixture into a paste with a wooden spoon. Return the pan to medium heat. Stir the mixture until it pulls away from the sides of the pan and is slightly shiny, about 3 minutes.
• Transfer the paste to a medium bowl and beat with a wooden spoon until slightly cooled, 2 to 3 minutes. Add the eggs one at a time, incorporating each one thoroughly before adding the next. Before adding the last egg, beat it in a small bowl. Add it by tablespoons to the mixture, just until the batter is smooth and tight. If the batter starts to get loose, do not add all of the last egg.
• Fill a large pastry bag fitted with an open tip with the batter. Pipe twelve 1-inch circular mounds about 2 inches apart onto the baking sheet. (Alternatively, use a large spoon to form the dough into mounds.) Dab the tops of each puff with a fingertip dipped in water to smooth.
• Bake in the middle of the oven for 20 minutes. Remove the puffs from the oven and use a sharp paring knife to pierce each side. Return the puffs to the oven until dry and crisp, another 5 minutes. Let cool on a rack. Repeat with the remaining batter.
• For the meringue frosting: Bring a few inches of water to a boil in a saucepan that can hold a mixing bowl above the water. Whisk the sugar, lemon zest and juice, egg whites, cream of tarter and salt by hand in the mixing bowl. Set the bowl above the boiling water and continue whisking until the mixture is hot to the touch and the sugar dissolves, 1 to 2 minutes. Transfer the mixture to a stand mixer fitted with the whisk attachment and beat at medium-high speed until the meringue is cool and holds a soft peak, about 5 minutes. Add a few drops of desired food coloring if using and continue beating until it holds stiff peaks.
• To assemble: Fit a pastry bag with a 1/4-inch round tip (a long eclair filling tip works great for this) and add the frosting to the bag. Insert the tip into the slit in the side of each puff and fill with frosting.
• Melt the white chocolate in a bowl over a pot of simmering water or in a microwave. Start by dipping a small bit of each puff into the melted white chocolate. Create an even round layer with the puffs on a 12- to 14-inch serving platter, using the chocolate to adhere. Place the platter in the refrigerator and allow to set for 10 minutes. Repeat with additional layer of puffs on top of the first, decreasing in size to create a "tower" effect and reheating the white chocolate to melt as needed. In between each layer, place the plate back in the fridge and allow to set for 10 minutes. When you reach the top, use the remaining white chocolate to drizzle over the top of the tower. Return the platter to the fridge and remove 20 minutes before you are ready to serve.

CROQUEMBOUCHE

Steps:

• For the Cream Filling: Prepare the cream fillings: Sprinkle the gelatin over 1/4 cup cold water in a bowl and set aside to bloom.
• Place the milk in a pan. Halve the vanilla beans lengthwise; scrape out the seeds with a paring knife, then add the seeds and pods to the milk. Bring to a simmer, then cover and remove from the heat.
• Whisk the egg yolks, sugar, cornstarch and salt in a medium bowl until smooth.
• Remove the vanilla pods from the milk. Gradually whisk one-third of the warm milk into the egg mixture.
• Whisk the egg mixture into the remaining milk in the pan. Cook over medium heat, whisking constantly, until the mixture boils and thickens, 6 minutes. Continue boiling until the mixture is custard-like, 3 minutes.
• Remove the pan from the heat. Slice the butter into pieces and whisk into the custard, then stir in the gelatin mixture.
• Microwave the chocolate until melted, 2 to 3 minutes, stirring. Mix 2 tablespoons hot water with the espresso. Transfer half of the cream filling to a bowl, then stir in the chocolate and espresso.
• Transfer the remaining cream filling to another bowl. Press plastic wrap directly onto the surface of the chocolate and vanilla creams and refrigerate until cold and firm, at least 2 hours.
• When ready to fill the puffs, whip the heavy cream to soft peaks with a mixer. Fold half into the vanilla cream filling and half into the chocolate filling.
• Transfer each filling to a large pastry bag with a 1/4-inch tip and set aside. (To do this cleanly, cuff the open end of the pastry bag over your hand.)
• For the Pastry Puffs: Unfilled puffs can be frozen for up to a week. To re-crisp, thaw, then brush with a beaten egg; bake 5 minutes at 350 degrees.
• While the fillings chill, make the pastry puffs: Preheat the oven to 450 degrees. Bring 1 1/2 cups water, the butter, sugar and salt to a simmer in a saucepan over medium heat, stirring to melt the butter.
• Remove from the heat and stir in the flour with a wooden spoon to make a paste. Return to the heat and cook, stirring constantly, until the paste is shiny and pulls away from the pan, 6 to 7 minutes. Cool slightly.
• Transfer the paste to a stand mixer and beat with the paddle attachment on medium-low speed to cool, 1 minute. Beat in the eggs one at a time. Scrape down the sides of the bowl as needed.
• Transfer the dough to a large pastry bag with a 1/2-inch tip. Line 2 baking sheets with parchment paper, dabbing a bit of dough under the corners to keep the paper in place. Pipe 1 1/2-inch balls of dough onto the paper (about 48 total).
• Smooth the dough peaks with a wet finger. Bake until puffed, 15 to 20 minutes, then lower the temperature to 350 degrees and bake until golden, 15 minutes. Turn off the oven; keep the puffs inside 10 minutes to dry out. Pierce each puff with a dry piping tip; transfer to a rack to cool.
• To Assemble: Fill half of the puffs with chocolate cream and half with vanilla: Insert the tip of the pastry bag into the hole and squeeze until full. Chill the filled puffs 30 minutes before assembling the tower.
• Make the caramel: Mix the sugar, corn syrup and 1 cup water in a saucepan, cover and bring to a boil over high heat; don't stir. Uncover and boil, swirling the pan, until the syrup turns deep amber, 20 minutes.
• Immediately dip the bottom of the saucepan in a large bowl of ice water for a few seconds to stop the cooking.
• Transfer the caramel to a liquid measuring cup and cool slightly (it should still be liquid). Be careful-the caramel will still be hot!
• Draw a 7-inch circle on parchment paper. Partially dip each filled puff into the caramel and let the excess drip off. Arrange the puffs around the circle. If the caramel hardens, microwave until soft, 45 seconds.
• Fill the base circle with more puffs for stability, then continue building a conical tower of smaller circles. Top the tower with a single puff. Line your work surface with parchment paper-the next step can be messy.
• Dip the tip of a fork into the caramel and quickly wave it in circles around the tower to create a web of caramel strands. Repeat. Let set, then slide two spatulas under the paper and transfer the croquembouche to a platter. Tear off the excess paper around the base.
• To serve, crack the caramel web with the back of a knife, then dismantle the tower and transfer the cream puffs to plates.

CROQUEMBOUCHE

Steps:

• Preheat the oven to 425 degrees. In a large saucepan, bring the water, butter, salt, and sugar to a rolling boil over medium-high heat. When it boils, immediately take the pan off the heat. Stirring with a wooden spoon, add all the flour at once and stir hard until all the flour is incorporated, 30 to 60 seconds. Return the pan to the heat and cook, stirring, 30 seconds to evaporate some of the moisture.
• Scrape the mixture into a mixer fitted with a paddle attachment (or use a hand mixer). Mix at medium speed. With the mixer running, and working 1 egg at a time, add 6 of the eggs, stopping after each addition to scrape down the sides of the bowl. Mix until the dough is smooth and glossy and the eggs are completely incorporated. The dough should be thick, but should fall slowly and steadily from the beaters when you lift them out of the bowl. If the dough is still clinging to the beaters, add 1 or 2 more eggs, and mix until incorporated.
• Using a pastry bag fitted with a large plain tip, pipe the dough in big kisses onto a parchment lined baking sheet. Whisk 2 eggs with 3 teaspoons of water. Brush the surface of the dough with the egg wash to knock down the points (do not use all the egg wash.) Bake 15 minutes, then reduce the heat to 375-degrees and bake until puffed up and light golden brown, about 20 minutes more. Try not to open the oven door too often during the baking. Let cool on the baking sheet. The recipe can be made up to this point and frozen in plastic bags. Filling: In a medium saucepan, heat the milk and vanilla bean to a boil over medium heat. Immediately turn off the heat and set aside to infuse for 10 to 15 minutes. In a bowl, whisk the egg yolks and sugar until light and fluffy. Add the cornstarch and whisk vigorously until no lumps remain. Whisk in 1/4 cup of the hot milk mixture until incorporated. Whisk in the remaining hot milk mixture, reserving the empty saucepan.
• Pour the mixture through a strainer back into the saucepan. Cook over medium-high heat, whisking constantly, until thickened and slowly boiling. Remove from the heat and stir in the butter and any flavorings if you want to make a different flavor like chocolate or coffee. Let cool slightly. Cover with plastic wrap, lightly pressing the plastic against the surface to prevent a skin from forming. Chill at least 2 hours or until ready to serve. The custard can be made up to 24 hours in advance. Poke a hole with a plain pastry tip in the bottom of each cream puff and pipe it full of the custard.
• Caramel: Dissolve the sugar in a saucepan with the water, making an "X" through the sugar with your finger to allow the water to slowly soak into the sugar. Boil to make a light golden caramel then dip the bottom of the pan in an ice bath to stop the cooking. Dip the sides of the puffs in the caramel and stick them together (approximately 20 cream puffs) in a circle, tops facing out. Make a second row on top of the first but a bit smaller to draw the circle in and create a tower of cream puffs. Check it from all sides occasionally to make sure it's straight. When it's finished, drizzle it with caramel all over. You can also stick on decorative elements with the caramel in the crevices, like candied violets, gold balls, gum paste flowers, sugar covered almonds, etc.

CROQUEMBOUCHE

Steps:

• Arrange a rack in the middle of the oven and preheat to 375 degrees F. Line a baking sheet with parchment paper.
• For the craquelin: Add the butter and sugar to a stand mixer bowl fitted with the paddle attachment and beat until combined. Add the flour and beat to combine. Stir in a few drops of food coloring of choice and beat until uniform in color. Scoop the paste out onto a sheet of parchment paper with a rubber spatula. Cover with another piece of parchment paper and use your hands to press out into an even sheet. Then roll gently a few times with a rolling pin to flatten to an even 1/8-inch thick. Transfer to a baking sheet and freeze for 20 minutes. When the craquelin is frozen, remove it from the freezer. Peel the top piece of parchment off and cut rounds with a 3/4-inch round cutter.
• For the choux dough: Meanwhile, combine the butter, sugar, salt and 2 cups water in a medium saucepan over low heat. Once the butter has melted, bring it to a boil over medium heat. As soon as it boils, remove the pan from the heat and sift the flour directly into the pan. Stir the mixture into a paste with a wooden spoon; you will have to beat it hard. Return the pan to medium heat. Stir the batter continuously until it pulls away from the sides of the pan and is slightly shiny, about 3 minutes.
• Transfer the batter to a stand mixer bowl fitted with the paddle attachment and beat until slightly cooled, about 3 minutes. Add the eggs, one at a time, incorporating each one thoroughly before adding the next.
• Fit a large pastry bag with a plain round tip and fill with the choux dough. Pipe twelve 2-inch circular mounds, about 2 inches apart, onto the prepared baking sheet. If the batter has a peak, dab it smooth with a wet fingertip.
• Beat the egg yolk with 1 tablespoon water and brush the surface of the puffs with the beaten yolk. Using a small offset spatula, gently lift the craqulin rounds off the parchment and place on top of the cream puffs. Bake on the middle rack for 20 minutes, then reduce the oven temperature to 325 degrees F and continue baking until the puffs are golden brown, light, airy and crisp, 30 to 35 more minutes. If the cream puffs still don't feel completely dry and crisp at the end of the baking time, poke a hole in the bottom with a paring knife and place them back into the oven for a few more minutes to crisp up. Remove from the oven and cool completely on a wire rack.
• Fill a pastry bag with a small plain tip with the Vanilla Pastry Cream. Fill each puff with the pastry cream from the hole in the bottom.
• To assemble: Mix the sugar, corn syrup and 1 cup water together in a heavy-bottomed pot and bring to a boil. Continue to boil until it reaches the hard crack stage at 300 degrees F.
• Use the hot syrup to adhere the puffs to about a 16-inch foam cone covered in foil, or pile up to form a mound. If the hard candy caramel gets too thick, heat it gently.
• Whisk together the sugar, cornstarch and salt in a saucepan. Add the milk, eggs and vanilla bean seeds and whisk to combine. Turn the heat to medium-high.Whisk often to keep it from sticking to the bottom of the pan. Once thick, after about 10 minutes, turn off the heat, add the butter and stir until combined.
• Pour the pastry cream into a bowl and cover with plastic wrap directly on the surface. Place in the fridge to cool completely, about 2 hours.

CROQUEMBOUCHE

Steps:

• Three days ahead (or 1 month and freeze): preheat the oven to 200C/gas 6/fan oven 180C. Lightly butter 3 large baking sheets. Sift the flour onto a large square of greaseproof paper. Put the butter in a large, heavy-based saucepan with 450ml/3⁄4pint water and gently heat until the butter has melted. Bring to the boil then immediately tip in the flour, all in one go. Beat with a wooden spoon until the mixture forms a ball that comes away from the sides of the pan. Leave to cool for 5 minutes.
• Beat in the eggs, a little at a time, beating well between each addition, until the mixture is glossy and only just holding its shape. You may not need to add all the beaten egg. Spoon and pack half the mixture into a large polythene freezer bag. Twist the opening to secure and snip off a 1cm tip from the corner (or use a piping bag and 1cm plain nozzle).
• Pipe small rounds, about 2cm in diameter, on to the baking sheets, trimming the paste from the bag with a knife. Leave room between them to allow for spreading. You should end up with about 75 rounds. Bake for 25 minutes, in batches if necessary depending on how many baking sheets you have, until well risen and golden, rotating the baking sheets half way through cooking. As soon as the pastry is cooked, make a 1cm slit on the side of each bun to let the steam escape. (This stops them turning soggy as they cool). Return to the oven for a further 5 minutes to dry them out, then transfer to a wire rack to cool. Store in an airtight container (or freeze).
• Make the cone. Make a pencil mark halfway along a long edge of the A1 card. Mark the halfway position along both short edges and draw a line from each point to the mark on the long edge. Attach one end of the string to the pencil and holding the other end at the point on the long edge, draw a curve from the point on one short side to the point on the opposite side. Cut out the card shape and use as a template to cut out the same shape in foil. Tape the foil over the card and roll up (foil inside), overlapping the straight edges to make a cone shape with a 20cm diameter opening. Secure with tape and snip 10cm off the point of the cone.
• Two days ahead: make the limoncello cream. Beat the egg yolks, sugar, flour, lemon zest and juice in a bowl to make a smooth paste. Bring the milk to the boil in a large, heavy-based saucepan. As soon as it reaches the boil, pour it over the egg mixture, stirring well. Return to the saucepan and cook over a low heat, stirring constantly until the sauce is very thick and bubbling. Stir in the liqueur and transfer to a bowl. Cover the surface with a circle of greaseproof paper to prevent a skin forming and leave to cool completely. Refrigerate until ready to use.
• The day before: if the buns are a bit soft when you take them out of the container, lay them in a single layer on baking sheets and re-crisp in a moderate oven for 5 minutes. Fill them sparingly with the limoncello cream by piping as before. You can always pipe in a little extra if you have any mixture leftover.
• Break the chocolate into a heatproof bowl and melt over a bowl of gently simmering water. (Or melt in the microwave on Medium for 2-3 minutes.) Give the chocolate an occasional stir until it has just melted. Turn off the heat.
• Rest the cone inside a vase or jug for support. Put a small bun into the point of the cone with the bun's base face up. Spoon 1 tsp of melted chocolate onto the base and secure two small buns over the first, again with base up. Spoon over another teaspoon of chocolate. It's a little difficult working at the tip of the cone but it gets much easier as the cone gets wider.
• Work up the cone, packing in the buns quite firmly, drizzling the chocolate (see left) and working in horizontal layers until the cone is filled. Make sure that each bun is firmly secured in place with chocolate before proceeding to the next layer and make sure the last layer forms a flat base for the cake. Keep the filled cone in the coolest place overnight.
• On the day: carefully invert the cone on to a flat serving plate and lift away the cone. Gently peel away the foil if it hasn't come away already. Put the remaining 100g/4oz sugar in a small heavy-based saucepan with 5 tbsp water. Heat very gently, stirring slowly until it has dissolved to make a smooth syrup. Take care not to splash the syrup up the sides of the pan or it may crystallise and solidify.
• Bring the syrup to the boil and cook for 4-6 minutes, watching closely until it turns a rich golden colour. Take off the heat and dip the base of the pan in cold water to prevent further cooking. Stand back as the pan will splutter noisily. Carefully dip the ends of the sugared almonds and roses in caramel and secure around the cake, scattering a few on the plate.
• Using a teaspoon, drizzle more caramel around the buns so that it falls in fine threads. If the caramel hardens before you've finished decorating, gently reheat it, taking care not to burn it. Finish with a dusting of icing sugar. To serve the cake, it is easiest if you have one server to break pieces off for the guests, starting from the top and working down.

PINK CROQUEMBOUCHE

Steps:

• Pate a Choux:Preheat oven to 450 degrees with rack in bottom third. Line three rimmed baking sheets with parchment. In a medium saucepan, combine butter, sugar, salt, and 1 cup water over medium heat; bring to a boil. Remove from heat. Using a wooden spoon, quickly stir in flour. Cook over medium-high heat, stirring constantly, until mixture pulls away from sides of pan and a film forms on bottom, about 3 minutes.
• Transfer to the bowl of an electric mixer fitted with the paddle attachment. Beat on low speed until slightly cooled, 1 1/2 to 2 minutes. With mixer on low, add eggs, one at a time, beating until each is fully incorporated and a soft peak forms when you touch dough with your finger.
• Transfer about half the dough to a large pastry bag fitted with a 5/8-inch plain tip (such as Ateco #808). Pipe into rounds, about 1 1/4 inches in diameter, onto prepared sheets, spacing about 2 inches apart. Smooth peaks with a wet finger, rounding tops to ensure even rising. Repeat with remaining half of dough. Place baking sheets in freezer while you repeat with remaining dough and make craquelin topping.
• Craquelin Topping:In the bowl of an electric mixer fitted with the paddle attachment, beat together butter and sugar on medium speed until fluffy, about 4 minutes. Beat in flour and salt. Add pink food color, a drop at a time, until desired color is reached. Roll out topping between two sheets of parchment to an 1/8-inch thickness. Transfer to a baking sheet and freeze 30 minutes.
• Using a 1-inch round cutter, cut out 72 rounds of craquelin dough and place one on top of each puff. Return to freezer.
• Transfer one baking sheet of puffs to oven; reduce oven temperature to 350 degrees. Bake until bottoms are golden brown and tops are crackled and crisp but not browned, 25 to 30 minutes. Repeat process with remaining baking sheets. (For crispier puffs, remove from oven after baking and use a small paring knife to create a small slit in the base of each puff. Turn off oven; return puffs to oven until crisp, 5 to 8 minutes. Let cool completely.)
• Strawberry Buttercream:Combine egg whites, sugar, and salt in the heatproof bowl of an electric mixer set over (not in) a pot of simmering water. Whisk until sugar is dissolved and mixture is warm to the touch and feels completely smooth when rubbed between fingertips.
• Transfer bowl to mixer fitted with the whisk attachment. Starting on low speed and gradually increasing to medium-high, beat until stiff (but not dry) peaks form. Continue beating until mixture is fluffy and glossy and bottom of bowl is cool to the touch, about 10 minutes. Reduce speed to medium-low and beat in butter, a few tablespoons at a time, until combined. Scrape down sides of bowl and continue beating until completely smooth. Beat in jam. Remove bowl from mixer and fold in chopped strawberries. Transfer to a pastry bag fitted with a coupler and a filling tip (such as Wilton #230).
• Insert pastry-bag tip into base of each puff; fill. Return filled puffs to baking sheets in a single layer as you work.
• Caramel:Prepare an ice-water bath. In a small saucepan over medium heat, bring sugar and 1/4 cup water to a boil, washing down sides of pan often with a wet pastry brush to prevent crystals from forming. Cook, without stirring, until sugar dissolves, about 5 minutes. Increase heat to high and cook, swirling pan gently to color evenly, until caramel is light amber, about 5 minutes. Remove from heat and dip bottom of pan in ice-water bath for a few seconds to stop the cooking. Use immediately.
• Working quickly, dip bottom of each filled puff in caramel (be very careful not to burn your fingers) and adhere puffs closely together in circular pattern, working upwards from the base to top of croquembouche mold.
• Use macarons and meringue kisses to fill in spaces between puffs, as needed.

MARTHA'S FAMOUS CROQUEMBOUCHE

Steps:

• Preheat oven to 400 degrees. Line 2 baking sheets with parchment.
• Make the puffs: Bring milk, water, butter, and salt to a boil in a medium saucepan over medium-high heat. Remove from heat, and whisk in flour. Return to heat, and cook, stirring constantly with a wooden spoon, until mixture pulls away from sides of pan, about 4 minutes. Transfer to the bowl of a mixer fitted with the paddle attachment. Mix on medium speed to cool slightly, about 1 minute. With machine running, add eggs, 1 at a time, beating well after each addition. Transfer dough to a pastry bag fitted with a 1/4-inch round tip.
• Whisk together yolk and heavy cream. Pipe about one hundred 1-inch puffs (about the size of a quarter) onto each prepared sheet. Gently brush with egg wash. Bake until puffs rise and are golden brown, 20 to 25 minutes. Let cool on sheets on wire racks. (Puffs can be stored at room temperature for up to 1 day.)
• Transfer caramel cream to a pastry bag fitted with a 1/4-inch round tip. Insert tip of pastry bag into base of each puff, and fill each. Return to sheets in a single layer as you work.
• Assemble the croquembouche: Dip top half of each filled puff into caramel (be careful not to burn your fingers), letting excess drip back into pan. Transfer to a parchment-lined baking sheet. Let stand until caramel is set.
• Carefully dip bottom half of 1 puff into caramel, letting excess drip into pan. Transfer puff, hot caramel side down, to a serving platter. Repeat with 9 more puffs, forming a connected ring as you work. Repeat with more puffs, layering rings to form a 6-layer pyramid, using 45 or 50 puffs total. (If the caramel begins to harden, reheat briefly over low heat.)
• Attach sugar cookies to sides and base of croquembouche, using royal icing or caramel as "glue."
• To make a second croquembouche, make another batch of caramel, and repeat with remaining filled puffs. (Alternatively, serve the remaining puffs on the side.) Serve immediately, or let stand at room temperature for up to 2 hours.

CROQUEMBOUCHE

Steps:

• For the puffs: Preheat the oven to 450 degrees F.
• Put the butter, sugar, salt and 1 1/2 cups water in a saucepan over medium heat and bring to a simmer, stirring to melt the butter. Remove from the heat and stir in the flour with a wooden spoon to make a paste. Return to the heat and cook, stirring constantly, until the paste is shiny and pulls away from the pan, 6 to 7 minutes. Cool slightly.
• Transfer the paste to a stand mixer and beat with the paddle attachment on medium-low speed to cool, 1 minute. Beat in the eggs 1 at a time. Scrape down the sides of the bowl as needed.
• Transfer the dough to a large pastry bag with a 1/2-inch tip. Line 2 baking sheets with parchment paper, dabbing a bit of dough under the corners to keep the paper in place. Pipe 1 1/2-inch balls of dough onto the paper. Smooth the dough peaks with a wet finger.
• Bake until puffed, 15 to 20 minutes, then lower the temperature to 350 degrees F and bake until golden, about 15 minutes. Turn off the oven; keep the puffs inside 10 minutes to dry out. Pierce each puff with a dry piping tip; transfer to a rack to cool.
• For the white chocolate: While the puffs are baking and cooling, bring a small saucepan of water to a simmer. Combine the white chocolate with the heavy cream in a small metal bowl and set it on top of the saucepan without touching the water. Heat, stirring, until the white chocolate melts and the mixture is smooth. Set aside to cool.
• For the whipped cream filling: Using a stand mixer or hand mixer and a whisk attachment, beat the heavy cream with the confectioners' sugar until soft peaks form. Whisk in the cooled white chocolate mixture.
• To assemble: Add the whipped cream filling to a pastry bag fitted with a medium tip. Fill each puff with a few tablespoons of the mixture through the hole already punched into it. Set aside.
• For the caramel: Mix the granulated sugar, corn syrup and 1 cup water in a saucepan, cover and bring to a boil over high heat; don't stir. Uncover and boil, swirling the pan, until the syrup turns deep amber, about 20 minutes.
• Immediately dip the bottom of the saucepan in a large bowl of ice water for a few seconds to stop the cooking. Transfer the caramel to a liquid measuring cup and cool slightly (it should still be liquid). Be careful--the caramel will still be hot!
• Draw a 7-inch circle on parchment paper. Partially dip each filled puff into the caramel and let the excess drip off (if the caramel hardens, microwave until soft, 45 seconds). Arrange the puffs around the circle on the parchment. Fill the base circle with more puffs for stability, then continue building a conical tower of smaller circles. Top the tower with a single puff. Line your work surface with parchment paper--the next step can be messy.
• Dip the tip of a fork into the caramel and quickly wave it in circles around the tower to create a web of caramel strands. Repeat. Let set, then slide 2 spatulas under the paper and transfer the croquembouche to a platter. Tear off the excess paper around the base.
• To serve, crack the caramel web with the back of a knife, then dismantle the tower and transfer the cream puffs to plates.

CANDY CANE CROQUEMBOUCHE

Steps:

• Make the pastry puffs: Preheat the oven to 450 degrees F and line 2 baking sheets with parchment paper. Bring 1 cup water, the butter, granulated sugar and salt to a boil in a medium saucepan. Remove from the heat and sift the flour directly into the pan; stir with a wooden spoon until a paste forms. Return to medium heat and cook, stirring constantly, until the paste is shiny and pulls away from the side of the pan, about 3 minutes.
• Transfer to a stand mixer fitted with the paddle attachment and beat on medium speed to cool slightly, about 2 minutes. Beat in 1 egg until incorporated, then beat in 1 more egg. Whisk the third egg in a small bowl, then beat into the dough, 1 tablespoon at a time, until just smooth and tight. (You may not need all of the third egg.)
• Transfer the dough to a pastry bag fitted with a 1/4-inch round tip. Pipe 1 1/4-inch rounds of dough onto the prepared baking sheets, about 1 inch apart; you should have about 50 puffs. (Alternatively, drop the dough in small mounds onto the baking sheets with a spoon.) Smooth the dough peaks with a dampened finger, then transfer to the oven and bake until puffed, 10 minutes. Reduce the oven temperature to 350 degrees F and continue baking until golden, 5 more minutes. Turn off the oven but leave the puffs inside to dry out, 5 to 7 more minutes. Remove from the oven and pierce a small hole in each puff with a paring knife to let steam escape; transfer to a rack to cool completely.
• Make the filling: Put the white chocolate in a medium heatproof bowl. Bring the heavy cream to a boil in a small saucepan, then pour it over the chocolate. Gently whisk until smooth and cool, about 7 minutes; whisk in the peppermint extract. Stir in the mascarpone until combined. Cover and refrigerate until thick enough to pipe, about 30 minutes. Transfer to a large pastry bag fitted with a 1/4-inch round tip.
• Insert the tip of the pastry bag into the hole in each puff and pipe in the filling. Transfer the filled puffs to a baking sheet; refrigerate at least 30 minutes or up to 2 hours.
• Make the icing: Whisk the confectioners' sugar and milk in a large bowl until smooth. Assemble the croquembouche: Dip the bottom of a puff into the icing, letting the excess drip off. Transfer the puff to a platter, icing-side down. Repeat with more puffs, arranging them side-by-side in a 7-inch circle. Fill in the circle with more puffs to stabilize the base of the tower. Continue building a conical tower of puffs, using the icing to hold them in place. (If the icing becomes too thick, whisk in more milk, 1 teaspoon at a time.)
• Dust the croquembouche with confectioners' sugar and sprinkle with crushed candy canes; chill until set, about 15 minutes.
