Ingredients

Chocolate base

100 gdark chocolate (70%), finely chopped
15 gunsalted butter
20 mlstrong espresso
2 mlvanilla extract
2egg yolks

Meringue and cream

2egg whites
25 gcaster sugar
80 mldouble cream, very cold
1 pinchpinch of fine salt

To serve

5 gdark chocolate, finely grated

Instructions

1
Prepare all ingredients before you start: finely chop the dark chocolate, separate the eggs carefully into yolks and whites, measure the espresso and vanilla, and chill a mixing bowl for the cream if possible. Because mousse sets quickly once combined, having everything ready makes folding much easier.
2
Melt the chocolate with the butter gently over a bain-marie or in short microwave bursts, stirring until smooth. Remove from the heat, then stir in the espresso and vanilla. Let it cool for 2-3 minutes; it should be fluid but no longer hot, so it will not scramble the yolks.
3
Whisk the egg yolks into the warm chocolate mixture one at a time until glossy and fully incorporated. The mixture will thicken slightly.
4
In a clean bowl, whisk the egg whites with the salt to soft peaks. Gradually add the caster sugar and continue whisking to medium-stiff peaks. The meringue should look glossy and hold its shape, but not be dry or clumpy.
5
In the chilled bowl, whip the cold double cream to soft peaks. Stop as soon as it holds a gentle peak; overwhipped cream makes the mousse heavy and grainy.
6
Fold one-third of the meringue into the chocolate mixture to lighten it. Fold in the remaining meringue in two additions using a spatula, scraping from the bottom and turning the bowl so you keep as much air as possible.
7
Fold the whipped cream into the chocolate mixture in two additions, just until no white streaks remain. Divide the mousse between 2 serving glasses or ramekins.
8
Chill for 15 minutes for a softly set, airy mousse that fits the time limit. Just before serving, top with the grated dark chocolate.

Notes

•For the best texture, use good-quality dark chocolate around 70% cocoa; sweeter chocolate makes the mousse less intense and softer.
•If you have extra time, chilling for 1-2 hours gives a firmer, more classic set than the quick 15-minute rest.
•Use very fresh eggs, and avoid getting any yolk into the whites or they will not whip properly.
•Serve as is, or with a few raspberries or crisp butter biscuits on the side.

Background

Mousse au chocolat became a classic of French dessert cooking in the 19th and early 20th centuries, prized for its light texture and deep chocolate flavor. Traditional versions often rely on whipped egg whites for lift, though many regional and modern variations include cream for extra richness and stability.
