Kaşkaval

Kashkaval[a] is a type of cheese made from the milk of cow's, sheep's, goat's or mixture thereof. In Turkey, Albania, Bulgaria, Kosovo, North Macedonia, Romania and Serbia, the term is often used to refer to all yellow cheeses . In English-language menus in Bulgaria, kashkaval is translated as 'yellow cheese' (whereas sirene is usually translated as 'white cheese' or simply 'cheese'). The name kashkaval is probably borrowed possibly comes from the Italian caciocavallo. Another theory claims that it is related to the Aromanian caș, 'cheese', but the kaval part remains unexplained.
