Champagne Chocolate Mousse Food

THE BEST CHOCOLATE MOUSSE

Steps:

• Whip 1 cup of the heavy cream to soft peaks in a medium bowl (see Cook's Note). Set aside.
• Add the egg, egg yolks, sugar, espresso powder, vanilla extract, salt and 1 tablespoon water to a medium heatproof bowl and whisk to combine. Set the bowl over a medium saucepan of gently simmering water (do not allow the bowl to touch the water). Whisk constantly until the mixture is pale, hot to the touch and has almost doubled in volume, about 4 to 6 minutes, scraping down the sides of the bowl occasionally with a rubber spatula, if necessary. Remove from the heat and continue whisking until cooled, about 2 minutes.
• Put the chopped chocolate in a medium heatproof bowl and set over the saucepan of gently simmering water (do not allow the bowl to touch the water). Stir occasionally with a rubber spatula until the chocolate is melted and smooth. Remove from the heat and gently stir for about 3 minutes to cool slightly.
• Whisk the egg mixture into the melted chocolate in 3 additions until combined. (The mixture may get very thick.) Using a rubber spatula, gently fold the whipped cream into the chocolate mixture in 3 additions until it is fully incorporated. It is important that the chocolate mixture is not warm to ensure that it combines smoothly with the whipped cream without seizing up.
• Divide the chocolate mousse among four 4-ounce ramekins and chill until firm, about 1 hour.
• Whip the remaining 3/4 cup cold heavy cream to stiff peaks. Top each chocolate mousse with whipped cream and serve. (For a softer texture, allow the ramekins to sit at room temperature while you whip the cream.)

CHAMPAGNE CHOCOLATE MOUSSE

Steps:

• In a heatproof bowl, combine the chocolate chips, butter and 2 1/2 tablespoons sparkling grape juice. Set the bowl over a pot of simmering water and stir until the chocolate is melted; let cool.
• In another heatproof bowl over simmering water, whisk the egg yolks, sugar and remaining 2 1/2 tablespoons juice until thick and warm but not cooked, 3 to 5 minutes. Remove from the heat and whisk in the melted chocolate; let cool to room temperature.
• Using an electric mixer, whip the heavy cream until soft peaks form; transfer 1/4 cup to a small bowl and refrigerate. Let the remaining cream stand until it reaches room temperature, then, using a large rubber spatula, fold into the chocolate mixture until smooth. Spoon into glasses and refrigerate until ready to serve.
• Stir the raspberry jam into the remaining 1/4 cup whipped cream and top each mousse with some of the raspberry cream.
