THIEBAUD PINK CAKE

Steps:

• To make the strawberry concentrate, wash, dry, and hull the strawberries. Cut the berries in half or quarter them if they are especially big.
• Combine the strawberries, water, and sugar in a medium nonreactive saucepan and bring the mixture to a simmer over medium-low heat, stirring to help the sugar dissolve. Turn down the heat to the low, cover, and simmer until the berries are soft, 8 to 10 minutes. Remove from the heat and let the berries rest, covered, for 5 minutes.
• Transfer the berry mixture to a fine-mesh sieve set over a medium nonreactive saucepan. Once all of the juice has drained, set the berries aside to use in another project. Bring the juice to a simmer over medium-low heat until it has reduced down to 1/4 cup (2.1 oz / 60 g), about 10 minutes, and set aside to cool.
• To assemble the pink cake, place the cooled cake on a flat, stable work surface. Using a long, serrated knife, slice off the rounded top of the cake so that it is perfectly level. An even, flat top is key to the look of this dessert.
• Using the serrated knife, split the cake horizontally into 2 even layers. Split each half in half again so that you have a total of 4 layers. Place the bottom layer on an 8-inch cardboard cake round or directly on the serving platter and set on top of a cake turntable, if you have one. Generously brush the surface of the cake with simple syrup.
• Prepare the buttercream by warming and whipping it to achieve a mayonnaise-like consistency (see Working with Buttercream ). Measure out 1/2 cup (2.6 oz / 73 g) of buttercream and, using an offset spatula, spread it evenly on the bottom cake layer, being careful not to let it blop over the sides. As you spread the buttercream, let a small wall (about 1/4 inch high) form around the outer edge, creating a well for the lemon curd.
• Evenly distribute 1/4 cup (2.1 oz / 60 g) of the lemon curd in the well. Set another cake layer on top and brush with simple syrup; spread with buttercream, creating a well, and fill with lemon curd just as you did with the first layer. Repeat with the third layer. Top with the final cake layer.
• If necessary, warm the buttercream once again. Measure out 1 cup (5.2 oz / 146 g) of buttercream and use the offset spatula to apply it as a crumb coat, a thin coating covering all surfaces of the cake; a crumb coat will seal the exterior of the cake to help prevent crumbs from marring the final frosting. (It's important to measure out buttercream specifically for the crumb coat so that the unused buttercream remains crumb free.) Refrigerate the cake for 10 to 15 minutes to set the crumb coat.
• Reserve about 1/2 cup (2.6 oz / 73 g) of buttercream for the top of the cake. Using an offset spatula, apply a thick layer of the remaining buttercream to the sides of the chilled crumb-coated cake. At this point, it's not important that the cake look pretty-it's most important that the buttercream be evenly distributed around the sides. With the cake sitting squarely in the middle of the turntable and with the offset spatula held vertically against the frosting, begin spinning the turntable. Keep the cake moving steadily in one direction and apply light pressure with the spatula; the buttercream will begin to even out. I like to imagine the spatula as the needle that stays steady while the record (or cake) spins round and round on the turntable. My goal is to make the sides perfect before adding any Thiebaud personality. Make sure to watch the vertical line of the cake; I find it helpful to look at the right side of the cake at eye level while spinning the turntable. You can add more buttercream to any spots that seem thin and whittle down any thick spots with the spatula.
• Once the sides are perfectly vertical and smooth, create as much or as little texture as you want in the buttercream. I constantly refer back to Display Cakes as I try to capture the casual, slightly imperfect look of Thiebaud's cakes onto my neatly frosted sides. It's not easy! While spinning the cake on the turntable, I often hold my offset spatula vertically and gently wobble it back and forth, or I take a quick swipe at the cake with the spatula blade as the turntable spins.
• When the sides are to your liking, you'll find a ring of buttercream standing up above the surface of the cake. Lightly "grab" the excess buttercream in one area with the offset spatula and pull it toward the center of the cake, spreading it toward the center. Repeat until you have a nice, clean edge all around.
• If necessary, warm the reserved buttercream, and then mound it up on top of the cake in the center. Using a small offset spatula, start from the center and begin smoothing out the buttercream, inching it closer and closer to the edge of the cake. I work fairly slowly when doing this in order to get a nice, voluminous lip of buttercream where the sides and the top of the cake meet, re-creating the ring that appears around the top edge of Thiebaud's pink cake.
• Place the raspberry in the center of the cake.
• The cake is best served immediately.
