BTW, for any of our friends across various bodies of water: The reason you would make a Christmas cake in August is so that when you pour all that lovely alcohol into the mix, it has a chance to really permeate the fruit-mince and ferment nicely, giving you a great boozy holiday dessert. Nice traditional Hertfordshire recipe below, and note the last instruction: "Keep feeding the cake with alcohol..." Great image, that -
