I always marinate the fruit for my Christmas Cake in brandy and then slosh a bit more onto the cake hot from the oven.  It makes a wonderfully rich cake which is great at Christmas, but is a bit too rich for other times of the year.  This recipe has a great tip to substitute the brandy with cold tea. I’ve turned a failed Christmas Pudding into a cake by doing that, but this is the recipe I’ve come across that suggests using it from the beginning.
