Swiss Meringue Buttercream Recipes

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:

• Continuously whisk egg whites and sugar in a large, heatproof bowl set over a pot of simmering water until the mixture is frothy, thick, and very hot to the touch (about 160 degrees F).
• Remove from heat and beat with a mixer on high speed. The mixture should then become cool and glossy and triple in volume.
• Beat in the butter, cut into 1/2 inch cubes, a few pieces at a time.
• Add the vanilla and beat until fluffy.

Steps:

• Put sugar and egg whites in the heatproof bowl of an electric mixer, and set over a pan of simmering water. Whisk constantly until sugar is dissolved, and mixture registers 140F on an instant-read thermometer.
• Transfer bowl to an electric mixer fitted with the whisk attachment. Beat on medium-high speed until fluffy and cooled, about 10 minutes. Continue beating until stiff, glossy peaks form.
• Reduce speed to medium-low; add butter by the tablespoon, beating well after each addition. Beat in vanilla and coconut if making buttercream for filling. Buttercream can be refrigerated in an airtight container up to 3 days or frozen up to 1 month. Bring to room temperature before using; beat on lowest speed until smooth, about 3 minutes.

Steps:

• In a small pot, bring 1 inch water to a boil over high heat.
• Place the egg whites and sugar in a medium metal bowl (or the metal bowl of a stand mixer) and place it on top of the pot, making sure that the bottom of the bowl does not touch the water. Whisk continuously (especially on the sides of the bowl) to prevent the egg whites from cooking, until the mixture reaches 160 degrees F and the sugar is completely dissolved, about 5 minutes.
• Remove the bowl from the heat, transfer it to a stand mixer fitted with the whisk attachment and whisk on high speed until soft peak forms, about 5 minutes.
• Switch to the paddle attachment on low speed and add the butter, one piece at a time. The buttercream might separate but keep the paddle going-the mixture will soon homogenize. Increase the speed to medium and paddle until silky smooth, about 5 minutes. Mix in the vanilla and beat for another 3 minutes.

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.

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:

• 1. Lightly whisk egg whites and sugar together over simmering water until egg-white mixture is hot to touch or a candy thermometer reads 140°F (60°C).
• 2. Pour hot whites into a room-temperature bowl and whip with a wire whip until double in volume on MEDIUM-HIGH speed. When the mixer stops, the meringue should not move around in the bowl. Meanwhile cut up butter into 2-inch pieces. (The butter should be slightly moist on the outside but cold inside.)
• 3. On your mixer, remove the whip and attach the paddle. Add half the butter (1 1/2 lbs or 680 g) into the bowl immediately and pulsate the mixer several times until the meringue has covered the butter completely. To pulsate the mixer, turn it on and off in a jerky motion. This forces the butter on the top to the bottom of the bowl. Add the balance of the butter (1 1/2 lbs or 680 g) and pulsate mixer several times. Slowly increase the mixer's speed, starting with the lowest speed and increase the speed every 10 seconds until you reach a MEDIUM-HIGH speed.
• 4. Continue beating until the mixture begins to look light and fluffy. Stop the mixer and scrape the bowl. Reduce speed to LOW. Add flavoring and continue to beat on LOW speed for 45 seconds. Then beat on MEDIUM-HIGH speed for an additional 45 to 60 seconds.
• 5. Leftover buttercream can be placed in plastic containers with lids and kept in the freezer for up to 3 months. Defrost completely (several hours) and rewhip before using.
• Note: In hot weather, use 2 lbs 10 ounces (1.19 kg) of butter and 6 ounces (710 g) of hi-ratio shortening. Hi-ratio shortening is emulsified and contains water.
• Storage: Store the icing in an airtight container and freeze for up to 3 months.
• Yield: 2 1/2 quarts (2.37 L)
