Patatnik or patetnik (Bulgarian: пататник or патетник) is a Bulgarian potato dish characteristic of the Rhodope Mountains in the country's central south. Patatnik is made of grated potatoes, onions, salt and a type of very mild mint called Gyosum in Bulgarian, all mixed and cooked on a slow fire. Some restaurants add sirene (white cheese) or eggs, but this is not traditional; some people also use savory and peppers.
