300mL or so whipping cream
115g or so cooking chocolate (about half a block)
3 tsp caster sugar
1. Melt the chocolate over a double broiler. Let cool for 5 minutes while beating the egg yolks, then whisk yolks into chocolate.
2. Beat whites until almost firm. Add sugar, then beat till whites form stiff peaks.
3. Beat cream until somewhat firm. Fold egg whites into cream. Don't handle too vigorously as whites will collapse.
4. Fold chocolate into cream mixture. Pour into individual serving bowls (martini glasses are a nice, classy touch!), and chill in fridge until firm.
