Czernina (Polish pronunciation:[t͡ʂɛrˈɲina]ⓘ, from czarny – "black"; also spelled czarnina or czarna polewka – "black soup") is a Polishsoup traditionally made of duckblood and clear poultry broth. Rabbit or pig blood can also be used as alternatives.[1][2] In English it can be called "duck blood soup".
Until the 19th century czernina was also a symbol in Polish culture. It was served to young men applying for the hand of their beloved. If the suitor was rejected, he would be served czernina. It is a plot element in Pan Tadeusz, a famous Polish epic poem by Adam Mickiewicz.
