What about the Irish one?
Would that be Clonakilty (West Cork) Black Pudding (they also do a smashing white one too)? I looked them up when I saw this thread. Shock horror, they make it with blood powder as well, and it still tastes amazing.
I’ve sometimes had “not nice” black pudding in a greasy spoon – assume it’s just been cheap shite bought from a wholesaler etc. Have tried Boudin Noir – lovely – but not so nice as to discount all others. Give me a couple of slices of Clonakilty black & white on a plate and I’d be happy out.
