The word pudding was around long before there was a Britain. It was much simpler back then. A pudding was anything you stuffed into an animal intestine or stomach and boiled the Hell out of it, (See: Holy Water).

At some point, when ingredients like eggs, sugar, and flour became common, the Brits kind of went off the rails and completely lost the whole thread as to just what is a pudding.

Oh great, that only narrows it down to the last millennium or so, and the meat of nearly every beast, fish, and fowl.

So… Scotland?

Edit: I say! With these comments, I’m really being taken on a grand tour!
