The tradition of making Christmas puddings dates back to the 16th century, and it's believed to have originated in England. The pudding was made with plenty of liquor, which helped to preserve it, and was often served as a dessert at special occasions.
As time went on, the recipe for Christmas pudding evolved, and different countries began to add their own unique twist. In Australia, for example, Christmas puddings often contain glace cherries and brandy butter. Meanwhile, in Ireland, they like to add a wee dram of whiskey to the mix!
