Best Lemony Swiss Meringue Buttercream Frosting Recipes

SWISS MERINGUE BUTTERCREAM

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.

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.

LEMON MERINGUE BUTTERCREAM

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.
