Hi there,
In the last few weeks, I have been trying to get a perfect chocolate mousse.
I have gotten very close but one thing is still eluding me.
As you can see in my photo, there's chocolate-y bits. Whatever I do, I never seem to be able to
perfectly incorporate those into the beaten egg whites.
Any tips, please? (my recipe is below)

6 eggs250g dark chocolate / couverture50g butter50g sugarvanilla/cointreau (optional)a lemon
Melt the chocolate in a bain-marie/sous-vide (55ºC).Remove the chocolate and incorporate the butter (which cools down the mix).Separate the eggs (keep 4 yolks and all 6 whites.)Whisk the 6 egg whites with a squeeze of lemon; add the sugar in the end to firm them. You should be able to inverse the bowl without losing the content!Add the yolks to the melted chocolate and mix immediately. The result should be smooth and shiny.Add a part of the egg whites to the chocolate mixture.Incorporate delicately by plunging the spatula and lifting the mixture without breaking the bubbles.Add the chocolate mixture to the rest of the egg whites.Continue incorporating delicately.
