What's your favourite version (flavours, decorations, etc.)? I usually make a couple of yule logs each Christmas: one to bring to a pot luck and another to bring to work or to give to someone. I've used pretty much the same formula (inspired by Canadian Living or Chatelaine) with variations for the last five years or so. It's a chocolate genoise filled with a mascarpone mousse and covered with a dark chocolate ganache. I decorate with marzipan mushrooms and holly, icing sugar and real ribbon. I think I'll probably do meringue mushrooms this year because it's cheaper, but I do love playing with that marzipan. The flavours of the cake and filling tend to change each year depending on my budget and what liquers I have available. My faves have been Frangelico and Grand Marnier (not in the same cake). For whatever reason, this cake always has a light, melt-in-your-mouth quality even if I use different recipes for the genoise and the filling. I can easily eat half on my own!
