Various baked items with a savory filling are specific for the Tatar cuisine. The oldest and simplest is "qıstıbí", also called "küzikmäk". This is an unleavened pancake folded into two and filled with cooked millet. Since the end of the 19th century, "qıstıbí" has been made with mashed potatoes. "Bäleş" made from unleavened or fermented dough is filled with pieces of fatty meat (mutton, beef, goose, duck, etc.) mixed with grains or potatoes. "Bäleş" used to be made for special occasions in the shape of a low truncated cone with an opening on top. Subsequently the name began to be used for ordinary pies with different fillings, similar to the Russian pirog. Another traditional Tatar pie is "öçpoçmaq", a triangular shell originally filled with a mixture of fatty meat and onions. Later pieces of potato began to be added to the filling. "Pärämäç" (peremech) is a round-shaped minced meat pie, fried and served hot sprinkled with melted butter. Except for the round shape, it is similar to the "çibörek" (cheburek) of the Crimean Tatars.
