Lemon and dark chocolate mousse

Pairing chocolate and citrus is bold but rewarding. The acidity of the lemon juice 'cuts' through the richness of the chocolate and cream, making the dessert feel lighter and less heavy. The airiness of the mousse comes from whisked egg whites and whipped cream, which must be carefully folded into the chocolate base.

Instructions

1

Melt the chocolate over a bain-marie (steam), then stir in the lemon juice and zest. Let cool to lukewarm.

Tip: Be careful the bowl doesn't touch the hot water, and no steam gets into the chocolate, or it will seize.
2

Whip the cream until stiff.

Tip: Do not over-whip (to butter), just until it holds its shape.
3

Whisk the egg whites with the salt and icing sugar until stiff peaks form.

Tip: Sugar makes the foam glossy and more stable.
4

Mix a little whipped cream into the lukewarm chocolate (to temper), then gently fold in the remaining cream and the egg whites.

Tip: Work with large folding motions using a spatula so the bubbles don't break.
5

Portion into glasses and chill for at least 2 hours.

Tip: The cocoa butter needs time to recrystallise, which gives the mousse its structure.

Recipe FAQ

Are raw eggs safe?
Use fresh, reliable eggs and wash the shell thoroughly before cracking. If concerned (e.g. pregnancy), use pasteurised egg whites.
Why is the mousse lumpy?
The chocolate was too cold when you mixed in the cream, causing the cocoa butter to set immediately. Equalising temperatures is key.
