        130gr                                             heavy cream

       

        Marshmallows

        60gr                                              egg whites

        190gr                                            sugar

        48gr                                              corn syrup

        120gr                                            water

        12gr                                              granulated gelatin

        as prefered                                   vanilla powder 

        a handful                                      corn flour with powder sugar

Marshmallows are preferably made first and may be left overnight to set uncovered and unrefrigerated. Before getting started with the kind of italian meringue they are made of, combine the gelatin with 48gr of the water and set it aside for at least 5min. In a small saucepan bring the rest of the water with syrup and sugar to boil watching its temperature rise with a candy thermometer. A few minutes before it reaches 120^oC start whipping the whites on low speed and as soon as it gets that hot remove from heat, add the gelatin and let it dissolve within a few seconds. With the mixer on high speed, pour the syrup alongside with the vanilla between the whip attachment and the sides of the bowl and into the quite foamed egg whites . Keep whipping until the bowl cools to slightly warm in the touch and finally spread the meringue on a silicone mat on the bottom of a 20x27cm frame or pan (for a thickness 2cm). Several hours later dust with powdered sugar and corn flour so that the marshmallows won't stick, and cut to small cubes. For the sponge cake beat butter until creamy, add 55gr of the sugar and then beat in the yolks one at a time. Mix the dry ingredients together and with the rest of the sugar whip the egg whites to stiff meringue. Fold the meringue and the flour mixture alternately into the butter, spread the batter on the bottom of a 20x24cm frame and bake at a preheated oven to 180^o-190^oC for 13min.

Continue with the marquise by melting chocolate in a bain marie, seperately beating the butter until soft and whisking the cream to soft peaks. Set them aside and prepare an italian meringue with the whites and 70gr of the sugar that may be moistened with the addition of a little water. Empty the bowl from the meringue and start whipping the yolks. Simultaneously prepare by the same way another syrup with the rest of the sugar and when it reaches 120C pour it into the egg yolks whipping on high speed until they completely cool down. Fold the whipped yolks into the butter and whisk in the chocolate. Finally incorporate the meringue and chantilly in several stages ,without deflating the mixture, and fill with the mousse a covered with plastic wrap on bottom 20x24cm frame. Freeze for a few hours. To assemble first spread cherry jam on the cake and optionally moisten with kirsch. You may either place the whole chocolate part on top, or cut it to individual pieces and roll them in cocoa powder as long as they're still frozen and hard. To complete, add the arshmallows on top and burn with a torch.
