Blood sausage, quite popular in Europe, is made(usually) from pigs' blood, suet, and a binder of some sort, often bread crumbs or/and oatmeal. Not to my taste, but the Euros seem to love it.
Looks like I only have to get up a bit earlier next time...
Us Polish call ours Kishka ;) And I love it! But you can keep Czarnina, blood soup! PU!
