Babka ziemniaczana is a savory potato cake. The potato is grated raw and mixed with fried bacon, onion, eggs and a little flour; some cooks add mushrooms, which are common in the region’s forests. The batter is baked in a pan, usually rectangular, for about one to one and a half hours, until the top is dark brown and the interior is firm. The name comes from babka, a tall yeasted cake, because of the shape it resembles.
Podlaskie, bordering Belarus and Lithuania, is Poland’s most diverse region in terms of origins and religions, and its cuisine blends Polish, Lithuanian, Belarusian, Jewish and Tatar traditions. It is a peasant, potato-based cuisine: simple and hearty. Within it, babka ziemniaczana is one of the best-known dishes; it is served in ready-meal houses and restaurants. The simplest versions used only potato, onion, flour and eggs, and bacon was added when meat was available, especially after pig slaughtering.
The dish has many names in the region, such as kartoflak, bugaj, rejbak and kugiel, and many variations. The same mixture, stuffed into a pig casing, becomes kiszka ziemniaczana. In 2005, babka ziemniaczana was added to the Podlaskie voivodeship’s List of Traditional Products. In the region it is sold in restaurants and ready-meal houses in rectangular slices.
