French Meringue Buttercream Recipes

Steps:

• Place the whole eggs and yolks in the bowl of an electric mixer fitted with a whisk attachment. Beat on medium-high speed until the eggs are pale yellow and thick, about 5 minutes. (The eggs will hold an indent made with your finger for a few seconds.)
• Meanwhile, pour the sugar and 1/3 cup water in a medium saucepan set over medium heat. Attach a candy thermometer to the side of the pan and bring to the soft-ball stage, without stirring, 240 degrees F.
• Begin whipping the eggs again on medium-high speed and slowly drizzle in the hot syrup, aiming the syrup between the side of the bowl and the beaters. Continue to whip until both the bottom of the bowl and the mixture are cool, 10 to 15 minutes. The mixture should be thick, but will not form a peak at this point. Beat in the salt.
• While still beating on medium-high, add the butter, a few pieces at a time. As the butter is added, the buttercream may appear to thin out some, but it will thicken into firm peaks once all of the butter is added. Beat in the vanilla extract.
• Use right away or refrigerate in an airtight container overnight. The buttercream may need to be beaten again to smooth out before using.

Steps:

• In a small saucepan over medium heat, bring sugar and water to a boil. Clip a candy thermometer onto the saucepan. Boil the syrup, brushing down the sides of the pan with a pastry brush dipped in water to prevent crystallization, until the syrup registers 240 degrees (soft-ball stage).
• In the bowl of an electric mixer fitted with the whisk attachment, beat egg whites on low speed until foamy. Add cream of tartar, and beat on medium high until stiff but not dry peaks form.
• With the mixer running, pour the sugar syrup down the side of the bowl (to prevent splattering) into the egg whites in a steady stream, and beat on high speed until the steam is no longer visible, about 3 minutes. Beat in butter, piece by piece. Add vanilla; beat until smooth and spreadable, 3 to 5 minutes. If it looks curdled at any point during the beating process, continue beating until smooth.

Steps:

• Place the egg whites and sugar into a metal bowl and set over a pan filled with about 2 inches of simmering water. Heat, stirring frequently, until the temperature of the egg whites reaches 140 degrees. They will feel very hot to the touch.
• Transfer the heated egg whites and sugar to a large mixing bowl or stand mixer. Mix at high speed (or as high as you can go without egg flying out of the bowl) until they have reached their maximum volume, 5 to 10 minutes. Mix on medium or medium-high speed while pinching off small pieces of butter and throwing them in. Mix in vanilla if using. The buttercream may look like it is breaking down, but keep on mixing and it will come back together.

Steps:

• Combine egg whites and sugar in a heat-safe bowl. Set the bowl over a pot of simmering water. Whip mixture until the temperature reaches 120 degrees F (49 degrees C) on a digital or instant thermometer and sugar is dissolved, about 5 minutes.
• Remove egg white mixture from heat. Continue to whip until soft peaks form and the meringue temperature has come down to 99 degrees F (37 degrees C) or lower, 4 to 7 minutes.
• Add butter to the meringue, 2 tablespoons at a time, whipping until incorporated and fluffy. Scrape the sides of the bowl and keep mixing until smooth, 5 to 8 minutes. Add vanilla extract and whip until incorporated.

Steps:

• One of the best-tasting buttercreams is also the easiest to prepare. See the end of the recipe for flavoring possibilities.
• Place egg whites, sugar and salt in medium-sized heatproof mixing bowl over a pan of simmering water and whisk gently and constantly until egg whites are hot (about 140 degrees) and sugar is dissolved, about 3 to 4 minutes. Remove from heat and whip by machine until thick and cooled, about 5 minutes. Beat in butter and continue beating until buttercream is smooth and spreadable. Use immediately or refrigerate, covered, for up to 5 days. Before using, bring buttercream to room temperature and beat smooth by machine. Beat in flavoring, a little at a time, and continue beating until buttercream is smooth, about 2 minutes longer (always flavor buttercream immediately before using it).
• Flavorings: Liqueur: 2 to 3 tablespoons liqueur, such as Grand Marnier or dark or light rum. Lemon: 2 to 3 tablespoons lemon juice. Coffee: 3 tablespoons instant coffee (espresso, if possible) dissolved in 2 tablespoons water, coffee or rum. Raspberry: 3/4 cup thick raspberry puree made by cooking down and straining a 10-ounce package of frozen raspberries. Chocolate: 6 ounces chocolate melted with 4 tablespoons water, coffee or milk and cooled.

Steps:

• Put egg whites and sugar in the heatproof bowl of an electric mixer set over a pan of simmering water. Whisking constantly, cook until sugar has dissolved and mixture is warm (about 160 degrees).
• Attach bowl to a mixer fitted with the whisk attachment. Beat egg white mixture on high speed until it forms stiff (but not dry) peaks. Continue beating until fluffy and cooled, about 6 minutes.
• Switch to the paddle attachment. With mixer on medium-low, add butter several tablespoons at a time, beating well after each addition. (If frosting appears to separate after all butter has been added, beat on medium-high speed until smooth again, 3 to 5 minutes more.) Beat in vanilla. Reduce speed to low; beat 2 minutes to eliminate air bubbles. Stir with a rubber spatula until smooth.

Steps:

• Make lemon curd:
• In a small heavy saucepan whisk together yolks and sugar and whisk in lemon juice, butter, and a pinch of salt. Cook mixture over moderately low heat, whisking, until it reaches boiling point, 5 to 7 minutes (do not let it boil). Strain curd through a fine sieve into a bowl and cool, its surface covered with a plastic wrap. Chill curd, covered at least 4 hours or overnight.
• Make buttercream:
• In a heavy saucepan combine sugar and water and bring to a boil, stirring until sugar is dissolved. Boil syrup, undisturbed, until it reaches 248°F on candy thermometer. While syrup is boiling, in a standing electric mixer beat whites with a pinch salt until foamy and beat in cream of tarter. Beat whites until they just hold stiff peaks and add hot syrup in a stream, beating. Beat mixture at medium speed until completely cool, 15 to 20 minutes. Beat in butter, 1 piece at a time, and beat until it is thick and smooth. (Buttercream will at first appear very thin but as more butter is beaten in, it will thicken.) Beat in lemon curd and salt, beating until smooth, and drizzle in framboise, 1 tablespoon at a time, beating. Buttercream may be made 4 days ahead and chilled in an airtight container or 2 weeks ahead and frozen in anairtight container. Let buttercream come completely to room temperature (this may take several hours if frozen) and beat before using.
