Ok... I have this recipe for Chocolate Mousse which I haven't tried yet.. thing is I'm unsure if this is normal or not, but it has egg white and egg yolk in it - mixed in separately at different times... but it's all raw - I get the egg white... but the egg yolk as well?? Anyone know more about this to help me?? Is this right??

Recipe is below:
Ingredients

200g dark eating chocolate, chopped
4 eggs, separated
1/2 cup caster sugar
300ml carton thickened cream, whipped
grated white chocolate curls, to decorate

Method

Place chocolate in a large heatproof bowl. Sit bowl over a pan of simmering water. Stir until chocolate is almost melted. Remove from heat and continue to stir until chocolate is smooth.

Beat egg whites and sugar in a small bowl with an electric mixer until sugar is dissolved and mixture is soft and glossy.

Beat egg yolks into chocolate mixture until well blended. Then, using a spatula, fold in egg white mixture until just combined. Then, fold in whipped cream until combined.

Spoon mousse into individual glasses or one large bowl. Refrigerate, covered, for several hours or overnight, until set.

Serve mousse decorated with white chocolate curls.

Tip
To change the flavour, make a jaffa mousse by stirring 2 teaspoons finely grated orange rind into egg yolk mixture. Or for a mocha mousse, stir 2 teaspoons coffee powder dissolved in 2 teaspoons hot water into egg yolk mixture. If you want to add brandy, coffee liqueur or any other flavour, allow about 1 tablespoon and add to the cream when you whip it.
