Chocolate Raspberry Swiss Roll Food

CHOCOLATE-RASPBERRY SWISS ROLL

Steps:

• CAKE: Preheat the oven to 350°. Butter a 10-by-15-inch jelly roll pan and line it with parchment paper, then butter the paper. In a medium bowl, beat the egg yolks with 1/4 cup of the granulated sugar and the vanilla until fluffy, about 3 minutes. Scrape the mixture into the bowl and fold in the flour.
• In a clean bowl using a clean whisk, beat the egg whites with the salt at medium speed until soft peaks form. Gradually add the remaining 1/4 cup of granulated sugar and beat until the whites are glossy. Using a rubber spatula, fold the whites into the yolk mixture until no streaks remain. Quickly fold in the melted butter. Spread the batter in the pan. Bake in the lower third of the oven for 20 minutes, or until golden and puffy. Let cool in the pan on a rack.
• Run the blade of a knife around the edge of the cake pan. Dust the cake with the confectioners' sugar and cover with a sheet of plastic wrap and a clean kitchen towel. Top with a cutting board and, holding both the board and pan, invert the cake. Rap the board against the table, then remove the pan and carefully peel off the paper.
• FILLING: In a large bowl, whip the cream with the granulated sugar, vanilla and salt to stiff peaks. Using an offset metal spatula, spread the raspberry jam on the cake. Spread the whipped cream evenly over the jam. Begin rolling up the cake from the long side, as tightly as possible, using the kitchen towel and plastic wrap to help shape the roll. Wrap the roll tightly in the plastic and transfer to a baking sheet. Refrigerate for at least 6 hours or, preferably, overnight.
• CHOCOLATE GLAZE: Put the chocolate in a bowl. In a saucepan, stir the cream, milk and sugar over moderate heat just until the sugar is dissolved. Pour the hot cream over the chocolate; let stand until the chocolate is melted, 3 minutes. Whisk until smooth, then whisk in the butter and let cool slightly.
• Discard the plastic wrap and transfer the cake to a rack. Pour half of the chocolate glaze all over the top and sides and spread it evenly with an offset spatula. Spread the remaining glaze all over the cake and refrigerate until set, at least 2 hours. Garnish the top with raspberries. Transfer the cake to a platter, cut into slices and serve.

CHOCOLATE SWISS ROLL

Steps:

• Place a rack in middle of oven; preheat to 350°F. Line bottom of a 17x12" rimmed baking sheet with parchment paper (do not grease pan or parchment). Separate yolks from 4 large eggs, room temperature, over a medium bowl to catch egg whites. Place yolks in a large bowl and set aside.
• Add 1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt, ½ tsp. cream of tartar, and ½ cup (100 g) granulated sugar to egg whites and beat with an electric mixer until sugar is dissolved and egg whites are glossy and stiff peaks form, 8-10 minutes. (You can also beat on medium-high speed in the bowl of a stand mixer fitted with the whisk attachment.)
• Add remaining ½ cup (100 g) granulated sugar to reserved egg yolks and whisk to combine, about 1 minute. Add ½ cup (32 g) unsweetened cocoa powder, preferably Dutch-process, ⅓ cup vegetable oil, 1 tsp. vanilla bean paste or extract, and ⅓ cup room-temperature water and whisk until cocoa is fully dissolved. Sift ½ cup (58 g) bleached cake flour and ½ tsp. baking powder over, then whisk vigorously to combine.
• Add one fourth of meringue to cocoa mixture and mix thoroughly (you can use either a whisk or rubber spatula). Add remaining meringue in 3 batches, gently folding after each addition until only a few streaks of meringue remain (err on the side of mixing slightly less rather than more to keep the batter billowy).
• Scrape batter into prepared baking sheet and, using a small offset spatula, gently spread to edges of pan, smoothing surface. Bake cake until top springs back when lightly pressed, 18-20 minutes (cake may start to shrink from sides of pan). Let cake cool in pan, 30-40 minutes.
• Using an electric mixer on medium-high speed, beat 2 cups heavy cream, 3 Tbsp. granulated sugar, 2 Tbsp. instant vanilla pudding mix, 1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt, and 1 tsp. vanilla bean paste or extract in a large bowl until medium-firm peaks form, about 4 minutes. (Or, use a stand mixer fitted with the whisk attachment, about 1 minute.)
• Run a small offset spatula along edges of pan to release cake from sides. Place a wire rack (same size as cake and rimmed baking sheet) on top of cake and flip over to invert cake onto it; remove baking sheet. Carefully peel away parchment paper (start from a long edge where it might be embedded in the cake and pull gently to ensure you don't tear cake); discard. Place a clean sheet of parchment on top of cake and flip cake over so wire rack is now on top; remove wire rack.
• Dollop filling over surface of cake. Using spatula, smooth cream evenly over cake, working all the way to the edges. Starting from a short end and using parchment as a guide, roll up cake. Transfer cake, seam side down, to a platter and chill until filling is set, at least 30 minutes and up to 4 hours.
• Using a serrated knife, trim ¼"-½" off both ends of cake to create clean edges; discard (or consider them a snack!). Using a small fine-mesh sieve, dust top of Swiss roll with powdered sugar. Slice with serrated knife to serve. Do ahead: Cake (without powdered sugar) can be assembled 2 days ahead. Tightly wrap and keep chilled. Dust with powdered sugar just before serving.
