Whole Egg Lemon Buttercream Food

WHOLE-EGG LEMON BUTTERCREAM

Steps:

• Bring 1 cup water to just below a simmer in a medium saucepan over medium-low heat. Using a handheld whisk, combine eggs, sugar, and salt in the bowl of a stand mixer. Place bowl on top of saucepan (it should not touch water) and cook egg mixture, whisking constantly, until lightened in color, thickened slightly, and an instant-read thermometer registers 160°F. Remove from heat and beat with stand mixer fitted with the whisk attachment on medium speed until completely cooled and tripled in volume, about 10 minutes. Add butter, 1-2 Tbsp. at a time, beating well after each addition until fully incorporated. Add vanilla and lemon curd and beat on medium-low speed until just combined.
• Do Ahead
• Buttercream can be made and refrigerated up to 5 days in advance or frozen up to 1 month. To use refrigerated buttercream, let sit at room temperature until soft, at least 2 hours. Beat with stand mixer fitted with the paddle attachment on medium speed until smooth. If texture is not smooth, beat in a little water, 1 tsp. at a time. To defrost, transfer buttercream from freezer to refrigerator to thaw overnight. Then follow the instructions for using refrigerated buttercream.

ROSEMARY OLIVE OIL CAKE WITH LEMON BUTTERCREAM

Steps:

• Make the cake: Preheat the oven to 300˚ F. Coat two 8-inch round cake pans with cooking spray. Combine the sugar, 2 1/3 cups flour, the baking powder, salt and 2 egg yolks in a large bowl; beat with a mixer on medium-high speed until well mixed. Stream in 1 cup olive oil and mix about 30 seconds. Beat in the 3 whole eggs, one at a time. Stream in the milk and vanilla and mix until combined.
• In a separate bowl, combine the chopped rosemary, remaining 2 teaspoons olive oil and 3 teaspoons flour. Fold the rosemary mixture into the batter.
• Pour the batter into the cake pans. Bake until a toothpick inserted into the centers comes out clean, 20 to 30 minutes. Transfer to a rack and let cool completely in the pans.
• Make the lemon curd: In a small saucepan, combine 1/4 cup sugar, the egg yolk, lemon zest and juice, cornstarch and 1 tablespoon butter. Stir continuously with a rubber spatula until the mixture boils and thickens, about 1 minute. Transfer the lemon curd to a bowl and place a piece of plastic wrap directly on the surface to prevent a skin from forming. Refrigerate to cool.
• Make the buttercream: Set up a stand mixer with the whisk attachment. In a medium saucepan, heat the egg whites and remaining 1 cup sugar over medium heat until the mixture reaches 160˚ F and the sugar is dissolved. (You should not be able to feel any sugar granules and the mixture should be very warm, not hot, to the touch.)
• Pour the egg white mixture into the mixer bowl and whisk on medium-high speed until the meringue is three times its volume, holds firm peaks and has cooled to about 95˚ F, about 4 minutes. Beat in the remaining 4 sticks butter slowly, piece by piece, until smooth and blended. Beat in the salt and vanilla.
• Remove the lemon curd from the refrigerator and fold it into the buttercream until well combined.
• Assemble the cake: Transfer 1 cake layer to a cake plate. Spread some of the buttercream on top using an offset spatula. Top with the other cake layer. Cover the top and sides of the cake with a thin layer of buttercream (this is the crumb coat); refrigerate 15 to 20 minutes. Cover with the remaining buttercream.

BUTTER CREAM FROSTING I

Steps:

• Cream butter until soft. Add salt and part of sugar gradually, blending after each addition. Then add egg yolks and vanilla; blend well. Add remaining sugar, alternately with milk, until of right consistency to spread, beating after each addition until smooth. Makes 2 1/2 cups or enough frosting to cover tops and sides of two 8 or 9 inch layers.

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.
