One of the staples of traditional Polish cuisine, krupnioki śląskie is a blood sausage made with smoked pork, pig's blood, and buckwheat, combined with salt, pepper, allspice, onions, garlic, and marjoram. The origins of this prized Silesian delicacy can be traced back to the late 18th century.

Once enjoyed only on special occasions, the krupnioki blood sausages are nowadays available throughout the year and found in every Polish delicatessen. They are traditionally served hot, accompanied by bread, mustard, pickled vegetables, and a glass of strong Polish beer.
