For the Blunznradln, cut blood sausage into finger-thick slices 2. Whisk eggs with milk and a little salt, place flour and breadcrumbs in a soup plate for breading.
Turn black pudding dumplings first in flour, then in egg-milk mixture and finally in breadcrumbs. Melt the lard in a deep frying pan and fry the sausage rolls until golden brown. Drain.
Mix the sour cream with curd cheese, chives and salt and serve with the baked Blunznradln.
