The essential thing, surely, is to remember that 'pudding' is
essentiallly 'boudin' or 'bowel' - or something stuffed into bowel
skin.

According to the OED, the word was first recorded in English in 1305,
and it meant this sort of meaty pudding for a long time - 250 years.
Didn't start meaning a sweet pudding until around 1550, and then it was
the sort of sweet pudding that would have been steamed in a bag, like a
modern Christmas pudding.

One other interesting thing is that it was often used along with
'haggis' - very early on. Haggis is a good old English word, not
scottish at all. It's just that it's faded out of use in England, and
continued in Scotland.
