'Pieczonki is a dish traditionally originating from Poręba, a small town near Zawiercie. In Poręba, Silesian Voivodeship, the locals host an annual "Światowy Festiwal Prażonek". Prażonki are prepared from sliced or diced potatoes, braised with lard, onions, kiełbasa or alternatively with beets and carrots, covered with a leaf of cabbage. To continue, the ingredients are then tightly sealed in a special screwed container. Served with kefir and mizeria.
