Swiss Meringue Buttercream For French Almond Macarons Recipes

SWISS MERINGUE BUTTERCREAM

Steps:

• Combine egg whites, sugar, and salt in the heatproof bowl of a standing mixer set over a pan of simmering water. Whisk constantly by hand until mixture is warm to the touch and sugar has dissolved (the mixture should feel completely smooth when rubbed between your fingertips).
• Attach the bowl to the mixer fitted with the whisk attachment. Starting on low and gradually increasing to medium-high speed, whisk until stiff (but not dry) peaks form. Continue mixing until the mixture is fluffy and glossy, and completely cool (test by touching the bottom of the bowl), about 10 minutes.
• With mixer on medium-low speed, add the butter a few tablespoons at a time, mixing well after each addition. Once all butter has been added, whisk in vanilla. Switch to the paddle attachment, and continue beating on low speed until all air bubbles are eliminated, about 2 minutes. Scrape down sides of bowl with a flexible spatula, and continue beating until the frosting is completely smooth. Keep buttercream at room temperature if using the same day. If not, transfer to an airtight container and refrigerate up to 3 days or freeze up to 1 month. Before using, bring to room temperature and beat with paddle attachment on low speed until smooth again, about 5 minutes.
• To tint buttercream, reserve some for toning down the color, if necessary. Add gel-paste food color, a drop at a time (or use the toothpick or skewer to add food color a dab at a time) to the remaining buttercream. You can use a single shade of food color or experiment by mixing two or more. Blend after each addition with the mixer (use a paddle attachment) or a flexible spatula, until desired shade is achieved. Avoid adding too much food color too soon, as the hue will intensify with continued stirring; if necessary, you can tone down the shade by mixing in some reserved untinted buttercream.

ALMOND MACAROONS WITH SWISS MERINGUE BUTTERCREAM

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.
