Delicious delicate dark chocolate dessert with lemon liqueur. If you are not a supporter of the use of raw chicken eggs that are part of the mousse, they can be replaced with quail eggs.
Melt the chocolate pieces in the microwave (about 1 to 2 minutes at medium power). Stir until smooth. Add lemon liqueur, stir.
Separate the yolks from the whites. Beat the whites well with a mixer (until firm white mass). Mix yolks with chocolate. Add egg whites and beat until smooth (a couple of minutes). Cool completely.
Place the mousse in a serving bowl and refrigerate for at least 3 hours (or until the next day).
