kasseri

thumb|Greek PDO Kasseri

Kasseri (Greek: κασέρι, Turkish: kaşar) is a medium-hard or hard pale yellow cheese made from pasteurised or unpasteurised sheep milk and at most 20% goat's milk. "Kasseri" is a protected designation of origin, according to which the cheese must be made in the Greek provinces of Thessaly, Macedonia, Lesbos, or Xanthi, but a similar type of cheese is found in Turkey, Romania, and the Balkans, where it is known as kashkaval. The same cheese is made with cow's milk, but in that case it cannot be legally sold as "kasseri" in the EU and is instead sold under names that are particular to each producer.
