Black pudding is one of my favourite foods. It's the reason why I love the so-called English breakfast so much, though it's easier to find black pudding in Scottish and Irish cafes.

Honestly if iron wasn't toxic beyond a certain level, and if it wasn't generally inadvisable to eat an unvaried diet, I would probably substitute most of my meals for black pudding and scrambled eggs... in toasted bagels. Perfection.

And blodpudding (http://sv.wikipedia.org/wiki/Blodpudding) is still common in Sweden.

Korea has a version of black pudding as well, it's called soondae. Pig's blood, vermicelli noodles and spices encased in pig intestine. Pretty tasty.

The mix of black pudding and haggis, in a croquette-style breadcrumb wrapping, is particularly excellent.
