Sirene po shopski consists of white Bulgarian cheese and tomatoes baked in gyuveche, a traditional earthenware pot. The ingredients are layered in the pot, seasoned with herbs such as parsley, and finished with an egg on top. It is believed that the dish originates in the area around Sofia.
The reasons can be found in the name shopski, which refers to the Shopi people who live near the capital. This nutritious meal is usually served in the same earthenware pots in which it was baked, so each guest receives an individual serving.
