Dark Chocolate Mousse

Rich, frosting-like mousse is utterly delicious--for about two spoonfuls. Yet light and silky versions often lack decent chocolate flavor. Could we have the best of both worlds?

Why This Recipe Works

Gather Your Ingredients

Before You Begin

*

When developing this recipe, we used our winning supermarket brand of dark chocolate, Ghirardelli bittersweet, which contains about 60 percent cacao. If you choose to make the mousse a day in advance, leave it out at room temperature for 10 minutes before serving. Serve with very lightly sweetened whipped cream and chocolate shavings. A hand-held mixer can do the job of a standing mixer in this recipe, though mixing times may vary slightly. This recipe contains raw or undercooked eggs, which comes with inherent risks.

Instructions

1.

Melt chocolate, cocoa powder, espresso powder, water, and brandy in medium heatproof bowl set over saucepan filled with 1 inch of barely simmering water, stirring frequently until smooth. Remove from heat.

2.

Whisk egg yolks, 1 1/2 teaspoons sugar, and salt in medium bowl until mixture lightens in color and thickens slightly, about 30 seconds. Pour melted chocolate into egg mixture and whisk until combined. Let cool until just warmer than room temperature, 3 to 5 minutes.

3.

In clean bowl of standing mixer fitted with whisk attachment, beat egg whites at medium-low speed until frothy, 1 to 2 minutes. Add remaining 1 1/2 teaspoons sugar, increase mixer speed to medium-high, and beat until soft peaks form when whisk is lifted, about 1 minute. Detach whisk and bowl from mixer and whisk last few strokes by hand, making sure to scrape any unbeaten whites from bottom of bowl. Using whisk, stir about one-quarter of beaten egg whites into chocolate mixture to lighten it; gently fold in remaining egg whites with rubber spatula until a few white streaks remain.

4.

In now-empty bowl, whip heavy cream at medium speed until it begins to thicken, about 30 seconds. Increase speed to high and whip until soft peaks form when whisk is lifted, about 15 seconds more. Using rubber spatula, fold whipped cream into mousse until no white streaks remain. Spoon into 6 to 8 individual serving dishes or goblets. Cover with plastic wrap and refrigerate until set and firm, at least 2 hours. (The mousse may be covered and refrigerated for up to 24 hours.)
