Pecan Roulade With Praline Mousse Food

DEVIL'S FOOD CAKE WITH HAZELNUT PRALINE

Steps:

• Heat the oven to 200 degrees Celsius (nonfan)/375 degrees Fahrenheit. Line the bottom of 2 (20-centimeter/8-inch) cake pans (tins) with a removable base with parchment paper and grease the sides. Alternatively, grease the bottoms and sides of 2 (20-centimeter/8-inch) regular cake pans, line with parchment, and grease the parchment.
• In a large bowl, whisk together cocoa, flour, baking powder, baking soda, salt and sugars. In a separate bowl, add the oil, eggs and kefir, and whisk just to combine. Add to the dry mixture and use a spatula to gently fold through. Add the 3/4 cup plus 3 tablespoons/220 grams hot coffee and mix gently to combine. It'll look very runny at first, but will soon come together into a glossy, pourable batter.
• Divide the batter evenly between the two cake pans, about 21 ounces/600 grams per pan. Bake for 30 minutes or until a skewer inserted into the middle comes out clean. Set aside to cool for about 30 minutes, then slide a butter knife along the sides to help release the cake. Brush the tops lightly with the remaining 1 tablespoon/14 grams extra coffee (discard any extra).
• Invert one cake onto a board, remove the parchment, then invert it again onto a cake stand or the platter you intend to serve it on (domed side up now). Invert the other cake onto a board (don't remove the paper). Invert it again, onto a plate, so that it's paper side down. (This will help prevent it from sticking.) Set both cakes aside to cool completely.
• Make the praline: With the oven still at 200 degrees Celsius/375 degrees Fahrenheit, spread the hazelnuts onto a parchment-lined medium baking sheet (tray) and bake for 12 to 15 minutes, or until deeply golden, shaking the pan halfway through baking. Set aside, keeping the tray and parchment paper. You'll use them again later.
• Place a large saucepan over a medium-high heat and, once quite hot, sprinkle in a third of the caster sugar to cover the base. It should immediately start to melt at the sides but not brown too quickly. Swirl the sugar in the pan a little, then add another third of the sugar, allowing it to melt a little before adding the remaining third. Turn the heat down to medium and cook until the sugar is an amber caramel, stirring with a spatula just a couple times (but not much more). Add the hazelnuts and 1/4 teaspoon salt, stirring to coat, then quickly transfer the mixture to your parchment-lined tray and leave to cool completely.
• Once cool, roughly break apart the praline and add it to a food processor. Pulse a few times until you have very coarse crumbs, then measure out about 1/2 cup/75 grams of the mixture and transfer to a bowl. Blitz the remaining mixture in the food processor for about 5 minutes or until it turns into the consistency of a smooth nut butter, stopping to scrape the inside of the bowl as necessary. Transfer this to a separate bowl.
• Make the mascarpone cream: Add all the ingredients to a stand mixer and beat on medium-high speed for 1 1/2 to 2 minutes, or until you have medium peaks. Refrigerate if not assembling right away (you want it nice and cold).
• When ready to assemble, top the cake on your cake stand with half the cream mixture. Spoon over about 2 tablespoons of the smooth praline and gently swirl it through the cream with your spatula. Top with another 2 tablespoons of the praline, this time without swirling. Sprinkle with half the praline crumble. Carefully invert the other cake on top now, removing the paper. Top with the remaining cream and repeat the same process with the smooth praline and praline crumble. Serve right away, or refrigerate overnight to firm up the cream before serving. (The cake will keep refrigerated for up to 3 days.)

GINGER-PECAN ROULADE WITH HONEY-GLAZED PECANS

Steps:

• Make cake layer:
• Preheat oven to 350°F. Line bottom and sides of a 15- by 10- by 1-inch jelly-roll pan with foil, dull side up, and brush with melted butter. Dust pan with flour, knocking out excess.
• Finely grind pecans with cake flour, cocoa, spices, and salt in a food processor. Beat together yolks, brown sugar, and molasses with an electric mixer at high speed until mixture is very thick and pale brown and forms a ribbon when beater is lifted, about 2 minutes with a standing model and 5 minutes with a hand-held.
• Fold in pecan mixture gently but thoroughly. Transfer 1 cup batter to another bowl and fold in 1/4 cup melted butter, then fold butter mixture into remaining batter gently but thoroughly.
• Beat whites with cleaned beaters in another bowl until they just hold soft peaks (do not overbeat). Stir one fourth of whites into batter to lighten, then fold in remaining whites gently but thoroughly.
• Spread batter evenly in jelly-roll pan and bake in middle of oven until set and firm to the touch, about 12 minutes. Cool in pan on a rack and cover with plastic wrap.
• Make filling:
• Beat cream with sugar until it just holds stiff peaks, then fold in 6 tablespoons crystallized ginger.
• Assemble roulade:
• Put an 18-inch length of foil on a work surface and sprinkle with some sugar. Invert cake onto foil sheet and gently peel off foil from top. Spoon three fourths of whipped cream over cake, leaving a 1/2-inch border around edges.
• Beginning with a short side and using foil as an aid, roll up cake, jelly-roll fashion, and transfer, seam side down, to a platter.
• Just before serving, spoon remaining whipped cream on top of roulade and sprinkle with honey-glazed pecans and remaining crystallized ginger.

PECAN ROULADE WITH PRALINE MOUSSE

Steps:

• Line an 18 × 12-inch baking pan with parchment paper and lightly grease the parchment or spray it with nonstick spray. Preheat the oven to 375°F.
• Pulse the pecans in a food processor until you have a coarse meal. Transfer to a medium bowl and toss with the baking powder.
• Whip the yolks with 1/4 cup of the granulated sugar in an electric mixer at high speed until thick and pale. Stir into the nut mixture. Using a clean beater and a clean mixing bowl, whip the egg whites at medium speed until foamy. Whip at high until soft peaks begin to form. Gradually add the remaining 1/4 cup plus 2 tablespoons granulated sugar. Stop the mixer and pull the beater out slowly: if the whites leave stiff peaks in the bowl, the mixture is ready (it should be stiff but not dry).
• Fold the whites into the yolk mixture one half at a time. Avoid the urge to overmix. Spread the batter evenly into the prepared pan.
• Bake until light golden brown, 10-12 minutes. Remove the cake from the oven and immediately cover with a damp towel; cool completely.
• Put the sugar and water in a small, heavy-bottomed saucepan and place over high heat. Stir to combine. Put the cream in another small saucepan and bring it just short of a boil. Remove from heat and set aside.
• Bring the sugar mixture to a boil and then down to a steady simmer. When the liquid turns amber, swirl the pan. This will help it caramelize evenly. When it reaches a deep amber color, remove it from the heat and very carefully whisk in the cream. It will bubble up and steam, so watch those fingers! Return the pan to the heat and whisk to dissolve all the caramel. Refrigerate 1 cup of the praline syrup for the mousse filling. Add the vanilla and bourbon to the rest for your sauce.
• Cream the cream cheese by hand or in an electric mixer fitted with the whisk attachment. Slowly add the praline syrup, scraping the bowl frequently. Add the vanilla. Place the gelatin in a small bowl with about 1 tablespoon warm water. Add the rum to the gelatin and stir to dissolve. Fold a bit of the praline syrup into the gelatin, then fold the gelatin mixture back into the praline syrup. Fold in the whipped cream, one half at a time.
• Run a paring knife around the outside of the cake to release it from the sides of the pan. Lift the edges carefully, feeling under the cake to loosen it. Sift a thin layer of confectioners' sugar onto the top of the cake. Lay a piece of parchment the size of the cake across the top, then turn the pan over to release the cake onto the parchment. With the cake lying on the counter, carefully peel the parchment that is now on top off the cake.
• Spread the mousse on the cake, stopping 1/2 inch from the long edge. Starting with the long edge closest to you, begin rolling the cake up jelly roll style, using the parchment for support. Tuck the rolling edge of the cake in as you go to make it a little tighter and neater. Place the cake back on the baking pan and refrigerate to firm it up.
• To serve, sprinkle with confectioners' sugar, cut the slices about 1 inch thick, and serve with a generous drizzle of the reserved praline syrup. Garnish with fresh strawberries or peaches, if desired.
