Swiss Meringue Buttercream For French Almond Macarons Recipes

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:

• Place the egg whites and sugar in large metal mixer bowl set over simmering water. Whisk constantly until the sugar melts and the mixture is very thin and warm.
• Remove the bowl from the heat and whisk on high speed until stiff peaks form, about 5 minutes. Continue beating on low speed until cool, about 15 more minutes.
• Beat in small pieces of the cool but soft butter on low speed. The mixture may "curdle" before coming together. Add vanilla extract or other flavorings if desired. Rebeat occasionally while frosting the cake to maintain a smooth texture.

Steps:

• Wipe the bowl of an electric stand mixer and the whisk attachment with lemon juice to remove any trace of grease. Add sugar and egg whites to the bowl.
• Whisk sugar and egg whites together in the bowl of the stand mixer over simmering water, whisking constantly but gently, until temperature reaches 140 degrees F (60 degrees C), about 10 minutes. Return bowl to the stand mixer.
• Whisk sugar-egg white mixture in the stand mixer fitted with the whisk attachment until mixture is thick, glossy, and temperature of outside of bowl is room temperature. Change attachment to the paddle attachment and continue mixing on low speed. Add butter, 1 cube at a time; mix until silky-smooth. If mixture curdles, continue mixing and it will return to smooth.
• Pour vanilla extract and sprinkle salt into butter-sugar mixture; beat until fully incorporated.

Steps:

• Make macaroons:
• Put oven racks in upper and lower thirds of oven and preheat oven to 300°F. Line 2 large baking sheets with parchment paper.
• Finely grind almonds with confectioners sugar in a food processor.
• Beat whites with salt in mixer at medium-high speed until they just hold soft peaks.
• Reduce speed to medium, then add granulated sugar, a little at a time, beating, and continue to beat until whites just hold stiff, glossy peaks. Fold almond mixture in 2 batches into whites until just combined, then fold in vanilla and almond extracts. Transfer meringue to pastry bag and pipe 16 (1 1/2-inch-wide) mounds 1 inch apart on each lined baking sheet (32 total). Smooth tops of mounds with a wet fingertip.
• Bake, switching position of sheets halfway through baking, until macaroons are puffed and tops appear dry, 15 to 17 minutes. (Macaroons should be crisp on the outside and chewy on the inside.) Slide parchment with macaroons onto racks and cool 10 minutes, then peel macaroons from parchment, transferring to a rack to cool completely, about 15 minutes.
• Make buttercream:
• Vigorously whisk together whites, sugar, and salt in cleaned mixer bowl set over a 4-quart pot of barely simmering water until sugar is dissolved and mixture is warm. Put bowl in mixer and beat with cleaned whisk attachment at medium-high speed until whites hold stiff, glossy peaks. Continue to beat, scraping down side of bowl with a rubber spatula, until meringue is completely cool to the touch, about 5 minutes.
• With mixer at medium speed, gradually add butter 1 piece at a time, beating well after each addition until incorporated. (If buttercream looks soupy after some butter is added, meringue is still too warm. If so, briefly chill bottom of bowl in a large bowl filled with ice water for a few seconds before beating in remaining butter.) Continue beating until buttercream is smooth. (Mixture may look curdled before all of butter is added but will come back together by the time beating is finished.) Add vanilla and almond extracts and beat 1 minute more.
• Assemble cookies:
• Transfer buttercream to cleaned pastry bag and pipe about 1 tablespoon onto flat sides of 16 macaroons, then top with remaining 16 macaroons.

Steps:

• Start whipping egg whites slowly in the mixer until foamy. Increase the speed of the mixer and slowly start adding the sugar until all the sugar is incorporated. Once all the sugar is in, increase the speed of the mixer even more and whip until the mixture is shiny and stiff. You now have a meringue. You know when your meringue is done when you pull out the whip, hold it horizontally, and if you have what looks a "sparrow's beak" on the end of the whip.
• Replace the whip, turn the mixer on medium and start adding the butter a bit at a time. Once all the butter is incorporated, turn the mixer on high and let mix; depending on the weather, the buttercream could take anywhere from 5 to 15 minutes to form. You will know when it has formed when you hear the motor of the mixer start to slow down and whine a little bit; also, when you first add the butter, your meringue will break down and look weird and this is what you want. When the buttercream is done, the mixture will be homogeneous, consistent, and tasty.
• Remove the buttercream from the bowl and transfer to an airtight container. Buttercream can be kept at room temperature for a few days or in the refrigerator for a 1 to 2 weeks, but always use warm buttercream when icing a cake. To warm up the buttercream, put it back in the mixer using the whip or the paddle, and apply direct heat with a propane torch you can find at any hardware store.
