Black pudding is European. They call it blood sausage. There are variations of blood sausage in many European countries. I think we got the Scottish version in Guyana. Not sure where souse originated.
As with the language Afro Caribbean people took this dish and adjusted it to their tastes, adding seasoning and using rice. I had a black pudding in Barbados which was closer to what the Scottish would have introduced and it tasted terrible.
