Passion Fruit Swiss Meringue Buttercream Recipes

GENOISE WITH PASSION FRUIT SWISS MERINGUE BUTTERCREAM

Steps:

• Preheat oven to 350 degrees with rack set in the lower third. Spray a 9-by-3-inch round baking pan with nonstick cooking spray; line pan with a parchment paper round and spray again. Set aside.
• In a small saucepan, melt butter over medium-high heat until nut-brown in color, about 8 minutes. Remove pan from heat and pour butter into a large bowl, leaving any burned sediment behind; stir in vanilla and keep warm (110 to 120 degrees).
• Lightly whisk together eggs and sugar in the bowl of an electric mixer; set mixer over (but not touching) simmering water and heat, whisking constantly, until lukewarm to the touch. Transfer bowl to electric mixer fitted with the whisk attachment and beat on high speed until light, airy, and quadruple in volume, at least 5 minutes. Whisk 1 cup egg mixture into warm melted butter mixture; set aside.
• Sift together flour and cornstarch. Gently and quickly fold half the flour mixture into remaining egg mixture until all the flour is absorbed. Repeat process with remaining flour mixture. Fold in butter mixture to combine and transfer to prepared baking pan.
• Transfer pan to oven and bake until golden brown and starts to shrink slightly from the sides of the pan, 20 to 30 minutes. If possible, avoid opening the oven door until cake has baked at least 30 minutes, as cake is fragile and may fall. Remove cake from oven and unmold immediately onto a wire rack to cool. Let cool completely before cutting into layers and frosting with buttercream.

Steps:

• In the heatproof bowl of an electric mixer set over (but not touching) simmering water, combine egg whites and sugar. Cook, whisking constantly, until sugar has dissolved and mixture is warm to the touch (about 160 degrees).
• In the heatproof bowl of an electric mixer set over (but not touching) simmering water, combine the egg whites and sugar. Cook whisking constantly until sugar has dissolved and the mixture is warm to the touch (about 160 degrees).
• Switch to the paddle attachment. With mixer on medium-low speed, add butter, several tablespoons at a time, beating well after each addition. (If frosting appears to separate after all the butter has been added, beat on medium-high speed until smooth again, 3 to 5 minutes more.) Beat in vanilla. Beat on lowest speed to eliminate any air bubbles, about 2 minutes. Using a rubber spatula, gently fold in passion fruit curd 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.
