Mousse au chocolat noir et zest d’orange

Everyone needs a little chocolate in their life, or so my wife Claire tells me. The combination of chocolate and orange is one of my son’s favourites, too, so this dessert never lasts long in our house. You’ll need a good-quality chocolate for this: I recommend 66%– 70% pure cocoa, which has a slight bitterness and a hint of spice. One thing, though, watch out for the chocolate disappearing: it seems to evaporate in our house whenever my back is turned!
