The tradition in England is that a christmas pudding is made about a month before Christmas, and everyone in the household will stir the mixture at some point in its production and make a wish for the coming year while stirring.

Usually the pudding would be kept for a year, and the preceding years pud eaten at christmas, but this is unusual these days, with centrally heated houses and few proper larders left most people eat it the year they make it.

Traditionally "stir up Sunday" is the Sunday before advent, which this year is 26th Nov, so Long Firm Freddie is actually a bit previous. If you really want a recipe, and there are many, I'll happily post one.
