Bulz is a traditional dish created with cooked polenta that is shaped into balls and filled with a creamy stuffing. Subsequently, polenta balls are grilled, pan-fried, or baked until a crunchy, slightly charred crust forms on the outside. The most common filling is the combination of butter and soft sheep's cheese known as brânză de burduf.

Chunks of bacon or ham are often incorporated into the filling to create a more balanced meal. The grilling process allows the cheese to melt and transforms bulz into an incredibly satisfying dish. It is believed that bulz was initially prepared by the Romanian shepherds, who were the first to use an open fire in order to grill these flavorful balls.

Bulz is usually served with a generous serving of sour cream and butter, and it is recommended to top it with a fried egg. Depending on the size of the balls, bulz can make a hearty breakfast, a quick snack, but it can also be served as an accompaniment to main courses.
