Howard said "Roast turkey and Christmas Pudding are "traditional" only at Christmas. "

Obviously talking about UK tradition there, but even then ,as far as the pudding goes, that tradition only goes back as far as the nineteenth century. And "traditional" turkey at Christmas for the general populace probably only goes back to the twentieth century from all that I've read (notwithstanding Mr Dickens' references to the bird). (As far as I recall, in our family we didn't have turkey as a rule until I was in my early teens -it was too expensive),
As far as our own Bonfire Night/Guy Fawkes Night celebrations went roast bird of any description didn't feature in any that we had. Bonfire in the garden,smoke everywhere, fireworks, and the occasional toffee apple and baked potato yes ... but 46 lb turkeys? Never featured in any tradition for the night that I ever heard of.
