Chocolate orange mousse

A rich, airy dark chocolate mousse with orange zest folded through, a nod to the French classic mousse au chocolat. Just four ingredients and set in the fridge.

Ingredients

• 200 g Dark chocolate, 70%, broken up
• 4 Eggs, separated, British Lion stamped
• 40 g Caster sugar
• 1 Oranges, zest only, plus a few strips to decorate

Method

1. Melt the chocolate in a bowl over a pan of barely simmering water, then leave to cool for 5 minutes.
2. Beat the egg yolks and orange zest into the chocolate. It will thicken; that's fine.
3. In a clean bowl whisk the egg whites to soft peaks, then whisk in the sugar a spoonful at a time until glossy.
4. Stir a big spoonful of the whites into the chocolate to loosen it, then gently fold in the rest until no white streaks remain.
5. Spoon into small glasses or one bowl and chill until set.
