Opera cake with pecans

The opera is an iconic Parisian pastry built up in layers. In this recipe, the traditional butter cream has made room for a more intense pecan-flavoured butter cream. The dark chocolate ganache gives it a solid flavour. Can be served as dessert or sold in small, individual portions in pastry shops.
