Dark Chocolate Peppermint Mousse recipe

Break up the chocolate bar into small pieces and either melt carefully in the microwave (checking and stirring every 30 seconds) or melt in a heatproof bowl over a pan of simmering water. Leave to cool slightly.

Whisk the egg whites until forming soft peaks, then gradually whisk in the caster sugar until you have a glossy consistency.

Add a spoonful of the egg white mixture into the melted chocolate and stir vigorously to combine. If the mixture seizes slightly, add more egg white and stir again.

Gradually fold in the rest of the egg white mixture until no white remains.

Add a teaspoon of peppermint extract and stir gently to combine. Add another teaspoonful for a really minty taste. 

Spoon into individual serving dishes and top with fresh mint.
