I would like to introduce to everyone "Czernina"
What


It is a soup made from duck or goose blood, known as (char-NEE-nah), czernina and czarna polewka, is a Polish soup that originated as a way to use up every part of a slaughtered duck or goose. It gets its name from the word "black" -- "czarny" referring to its dark color. Typically made with dried fruits, blood and vinegar which prevents the blood from clotting at the same time giving it a sweet-sour flavor. In the past it was served to usuccessful Polish suitors from the maiden's parents to let them know their advances were not welcome.
