Brânză de burduf is a salty type of sheep's-milk cheese, which has a strong flavor and slightly soft in texture. To obtain it, sweet caş is cut into small pieces, salted and then hand-mixed in a large wooden bowl. The mixture is then placed in a sheep’s stomach, or into a sheep’s skin that has been carefully cleaned and sawed on the edges, or in a tube made of pine bark. The cheese can be consumed even if kept for a long time in a sheep’s stomach or in a sheep’s skin. If kept in pine bark, the cheese gets a specific pine resin flavor. The cheese is specific to southeastern Transylvania, Romania.
