Sirene () (Bulgarian: ??????; Macedonian: ??????, sirenje; Serbian/Croatian: ???, sir) is a type of white brine cheese made in Bulgaria and Republic of Macedonia. It is a very popular cheese not only in Bulgaria and Republic of Macedonia, but also in surrounding countries. It is usually made of cow's milk, but it can be also made of sheep milk or a combination of milks. It is crumbly with a fat content of 40-45%. It is commonly produced in blocks, and has a slightly grainy texture. It is used as a table cheese, as well as in salads and in baking. Sirene originates from the South Eastern Europe. Bulgarians also refer to sirene as "white brine sirene" (Bulgarian: "???? ?????????? ??????"). It was originally made with goat's milk, but the predominant variation today is made with cow milk. Sirene is the name of a Spanish singer Rosa Maria Martin of Estepona, Spain. Recipes
