✔ Icing
➤ Put the chocolate and the oil in a saucepan and gently melt in a double boiler.
➤ Pour the icing on the cake, still smooth with a spatula and refrigerate for at least an hour.
➤ To cut it, take a plastic plate to hold the side of the cake by holding it vertically and cut it with a knife also vertically going towards the plastic plate, so we do not crush it.

♦Tip: You can freeze the opera perfectly. Let it thaw for 1 hour in the refrigerator before tasting.
