Chocolate Mousse Imperiale Recipes

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.)

Steps:

• Melt the chocolate in the microwave in a microwaveable bowl, stirring every 30 seconds until just melted. Whisk the egg whites to soft peaks, scatter in the sugar and whisk again until the mixture forms stiff peaks when you lift the whisk out (around 30 seconds).
• Add a big tablespoon of the egg white to the melted chocolate and mix vigorously, working fast so the chocolate doesn't cool and harden. Then fold in the remaining egg whites carefully using a spatula or large metal spoon. Spoon into 4 glasses or ramekins and set in the fridge for 2-3 hours. Serve each with a dollop of crème fraiche and shavings of dark chocolate.

Steps:

• In a medium saucepan, whisk together egg yolks, 2 tablespoons sugar, and 3/4 cup heavy cream. Cook over medium-low heat, stirring, until mixture coats back of spoon, 3 to 4 minutes (do not boil). Remove from heat; whisk in melted chocolate and vanilla. Strain into a bowl; chill until cool.
• With an electric mixer, beat remaining 1 1/4 cups heavy cream with remaining 2 tablespoons sugar until stiff peaks form. Stir 1/3 of whipped cream into cooled custard mixture, then gently fold in the rest with a rubber spatula.
• Spoon into serving dishes; chill, covered, at least 30 minutes and up to 3 days. Bring to room temperature before serving.

Steps:

• Bring an inch of water to a boil in a medium saucepan. Combine the cream and chocolate in a large heatproof bowl. When the water boils, turn the heat to low so the water is barely simmering or just steaming. Set the bowl over the saucepan and melt the chocolate, gently stirring with a whisk now and then.
• While the chocolate melts, whisk the egg whites in a clean bowl using a stand mixer or electric hand mixer on medium speed. When the whites are foamy, add the sugar in a slow stream while whisking. Continue whisking until stiff peaks form. The whites should look glossy but not dry, and, when you lift the whisk from the mixture, a peak should form in the bowl and hold.
• Once the chocolate has melted completely, turn off the heat but leave the bowl over the saucepan. Holding the bowl with a kitchen towel, add the egg yolks one at a time, whisking after each addition. If the mixture looks broken, remove the bowl from the saucepan, cool for a minute, then add 1 tablespoon cream and whisk just until shiny and smooth. Whisk in the vanilla. (Don't worry if it still doesn't look completely smooth. It will come together in the next step.)
• Add a quarter of the beaten whites to the chocolate mixture and stir gently with a flexible rubber spatula until incorporated but still a little streaky. This will make it easier to fold in the remaining whites to create an airy mousse by gradually lowering the temperature of the chocolate (tempering) and making the mixture loose.
• Add the rest of the whites and fold them in by running the spatula from 12 o'clock on the bowl to 6 o'clock, then scooping up the chocolate on the bottom and gently folding it over the whites as you move toward 9 o'clock. Rotate the bowl 90 degrees and repeat. Continue folding just until the last streak of white disappears. It's OK if there are a few lumps of whites left. It's better to not deflate the batter by folding too much.
• Scoop into a pretty bowl or into individual cups or bowls for serving if you'd like. Otherwise, keep it in the mixing bowl. Refrigerate the mousse uncovered until cool, then cover and refrigerate for at least 4 more hours and preferably 24. The covered mousse can be refrigerated for up to 5 days.
• If you'd like to serve the mousse with whipped cream, whisk heavy cream until soft peaks form. A cup or two of heavy cream is plenty for this amount of mousse. Serve the mousse cold, straight from the refrigerator, with the whipped cream.
