SWISS MERINGUE BUTTERCREAM RECIPE

Steps:

• Place egg whites and sugar into the bowl of a stand mixer, whisk until combined.
• Place bowl over a pot with 1-2" of simmering water and stir constantly with a whisk until the mixture is hot and no longer grainy to the touch or reads 160F on a candy thermometer (approx. 3mins)
• Place bowl on your stand mixer and whisk on med-high until the meringue is stiff and cooled (the bowl is no longer warm to the touch (approx. 5-10mins)).
• Switch to paddle attachment (optional). Slowly add cubed butter and mix until smooth.
• Add flavorings as desired whip until smooth.

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:

• 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:

• 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:

• Place sugar and egg whites in the heat-proof bowl of an electric mixer. Set bowl over a pan of gently simmering water, and whisk until sugar has dissolved and egg whites are hot to the touch, about 3 minutes. Test by rubbing the mixture between your fingers; it should feel completely smooth.
• Transfer bowl to mixer stand. Using the whisk attachment, beat on high speed until mixture has cooled completely and formed stiff and glossy peaks, about 10 minutes.
• Add the butter, one piece at a time, and beat until incorporated after each addition. Don't worry if the buttercream appears curdled after all the butter has been added; it will become smooth again with continued beating. Add vanilla, and beat just until combined.
• Switch to the paddle attachment, and beat on the lowest speed to eliminate any air pockets, about 5 minutes. If using buttercream within several hours, cover bowl with plastic wrap, and set aside at room temperature in a cool environment. Or transfer to an airtight container, and store in the refrigerator, up to 3 days. Before using, bring buttercream to room temperature, and beat on the lowest speed with the paddle attachment until smooth, about 5 minutes.
