Chocolate Mousse

Separate eggs and yolks while eggs are cold. Place whites in a large bowl and yolks in a small bowl. Leave whites while you prepare other ingredients.

Yolks: Whisk yolks until uniform.

Melt chocolate and butter: Break chocolate into pieces and place in a microwave-proof bowl with the butter. Melt in the microwave in 30 second bursts, stirring in between, until smooth. (Stir in optional flavourings at this point, but read Note 6 first). Set aside to cool slightly while you proceed with other steps.

Whip cream: Beat cream until stiff peaks form, being careful not to over-whip (see video).

Whip whites: Add sugar. Beat whites until firm peaks form (see video, Note 5)

Fold together all ingredients - Fold egg yolks into cream using a rubber spatula – 8 folds max. Some streaks is fine.

Fold together all ingredients - Check chocolate temperature: The chocolate should still be runny but warm (min 35C / 95F; ideal 40C / 104F). If too cool or thick, microwave in burst of 5 seconds at a time until runny.

Fold together all ingredients - Pour chocolate into cream yolk mixture. Fold through – 8 folds max. Some streaks here are ok.

Fold together all ingredients - Add 1/4 of beaten egg whites into chocolate mixture. Fold through until incorporated – "smear" the spatular across surface to blend white lumps in – aim for 10 folds.

Fold together all ingredients - Pour chocolate mixture into egg whites. Fold through until incorporated and no more white lumps remain – aim for 12 folds max, but ensure there are no obvious egg white patches.

Fold together all ingredients - Divide mixture between 4 small glasses or pots. Refrigerate for at least 6 hours, preferably overnight.

Fold together all ingredients - To serve, garnish with cream and chocolate shavings. Raspberries and a tiny sprig of mint for colour would also be lovely!
