Chocolate Chestnut Roll Recipes

Steps:

• Preheat oven to 325 degrees F (165 degrees C). Line one 15 1/2 x 10 1/2 inch jelly roll pan with parchment paper and grease and flour lightly.
• Separate the eggs. Beat the whites with the cream of tartar until stiff. Gradually beat in 1/2 cup of the sugar.
• Sift the remaining sugar, cocoa, and flour together. Beat the egg yolks until thick and fold the flour mixture into them. Stir in vanilla. (The egg yolk mixture will be very stiff). Carefully fold the egg yolk mixture into the beaten egg whites. Evenly spread the batter into the prepared pan.
• Bake at 325 degrees F (165 degrees C) for 20 minutes. Let cake cool for 5 minutes. Turn cake onto a towel sprinkled with confectioner's sugar, peel off parchment paper and roll cake up with the towel. Let cake cool completely. Unroll cake and spread with the whipped cream. Roll again. Serve with Foamy Butter Sauce or Fudge Sauce. For variation, you can add 2 tablespoons of rum or your favorite liqueur to the whipped cream. Serves 8.

Steps:

• Place chocolate in a small bowl with 1/4 cup water. Set bowl in a pan of barely simmering water, stirring frequently until melted and smooth. Set aside to cool. Combine 1/2 cup, or more to taste, of chestnut cream into 1 slightly rounded cup of buttercream. Set aside.
• Assemble the Buche: Peel parchment liner from cake. Lift foil under cake and invert it onto a second sheet of foil. Remove the original foil, peeling away the browned genoise "skin" stuck to it. Moisten the cake with the rum, using a pastry brush. Spread chestnut buttercream evenly over the cake. Roll the cake tightly, the long way, into a "log" using the foil to aid you if necessary. Wrap log tightly in foil. Freeze until hard, or at least firm. The firmer the cake, the easier it will be to decorate. Log may be completed to this point, and kept frozen, up to 6 weeks. Stir chocolate mixture into remaining buttercream and refrigerate or freeze until needed. Finish and Decorate the Buche: Soften reserved chocolate buttercream and beat just until smooth. Unwrap the frozen log. Trim a fraction of an inch from each end to even the edges. Spread the log with most of the reserved chocolate buttercream. Do not frost the ends. Use a fork to texture the buttercream so that it resembles the bark of a tree. Dip a sharp knife in hot water, then wipe dry. Cut the diagonal "stump" off each end of the log. Set stumps aside. Transfer log to a serving platter. Affix stumps to the log. Cover bare spots with buttercream. Use the fork to touch up the bark effect as necessary. Decorate with sprigs of pine and meringue mushrooms. Store in the refrigerator. For best flavor and texture, remove Buche from the refrigerator at least an hour before serving.

Steps:

• Heat oven to 375 degrees. Melt chocolate and butter in a bowl set over boiling water until chocolate is nearly completely melted, then remove from heat and whisk mixture until smooth.
• In a mixing bowl, whisk egg yolks with half the sugar (1/4 cup/50 grams) and the salt until pale and thick. Stir in the warm chocolate and set aside.
• Put egg whites in a clean bowl with cream of tartar and beat until fluffy, then add remaining 1/4 cup/50 grams sugar and beat until whites are stiff but not dry.
• Stir chestnut flour and chopped chestnuts into the chocolate batter, then fold in 1/4 of the whites to lighten mixture. Fold in remaining whites and scrape batter into an unbuttered 8-inch springform pan, smoothing top if necessary.
• Bake for 25 to 30 minutes, until a toothpick inserted in the center of the cake comes out almost clean. Cool on a rack. It may sink and crack a bit on top - this is fine. Run a knife around the edge of cake to free sides and remove form. Transfer to a serving platter. (Cake may be stored, covered, at room temperature for up to 3 days.)
• To serve, whip cream with 2 tablespoons sugar to a very soft consistency. Spoon over top of cake and quickly spread with a spatula. Sprinkle with chocolate curls or cocoa powder.
