White Cheese - a particular variety of the increasingly-popular Greek Feta cheese now popular in many places. It originated on the Balkan Peninsula in a region called Trakia, which is the current day Southern Bulgaria. This Bulgarian sirene has much the same texture as the Greek feta. It is a brined cheese, produced from sheep or cows milk, and is both used on the table and as an essential part of other foods from Shopska Salata to Banitza. Feta Cheese is produced in many different countries, but Bulgarian-made Feta is generally held to be the best.
