Czernina (literally 'the black one') is one of Poland's most divisive dishes — a sweet-and-sour soup made from duck or goose blood, dried prunes and pears, vinegar, sugar, and the duck's broth. The Silesian and Pomeranian (Kashubian) regions both claim it. There's a folk tradition that a young man who came to ask for a girl's hand and was served czernina knew the answer was no — the family wouldn't waste a fresh-killed duck on him. Eaten on All Saints' Day and feast days.
A Silesian duck-blood soup with dried fruits — sweet-sour-savory, dark purple-brown. The Polish 'black soup' once used to politely refuse a marriage proposal.
Czernina's duck blood must be mixed with vinegar immediately after collection — without acid, the blood proteins coagulate within minutes. The dried fruits (prunes, raisins) add fructose that balances the iron-mineral taste of blood.
Variations
Silesian czernina uses duck blood; Kashubian version uses goose blood; Lithuanian version uses pig blood — three blood-soup traditions.

Ingredients
How it's made
5 steps · 3 hours
- 145 min
Make duck broth: simmer 1 duck (or duck pieces equivalent to 1.5 kg) with 1 onion, 1 carrot, 1 celery stalk, 8 black peppercorns, 3 bay leaves in 2.5L water for 90 minutes.
- 26 min
Strain broth (return to a clean pot, keep meat for serving). Reduce broth to ~1.5L over high heat.
- 390 min
Soak 100g pitted dried prunes and 50g dried pear in 200ml hot water 30 min; chop coarsely.
- 49 min
Whisk 200ml duck blood (fresh or frozen-thawed) with 100ml red wine vinegar to prevent clotting. Whisk in 50g sugar, 1 tsp ground allspice, ½ tsp cinnamon, ½ tsp ground cloves.
Watch outWhisk the vinegar into the blood the instant you have it — without the acid the blood clots into lumps within minutes and can't smooth back out.
- 530 min
Add dried fruit and soaking liquid to the broth; simmer 10 min. Off heat, slowly whisk in the blood-vinegar mixture until smooth. Reheat gently — do not boil. Serve with egg noodles or boiled potatoes.
Watch outPour the blood in off the heat and never let it boil — one real boil and it curdles into grains instead of a smooth, velvety soup.
