What is "markook"

Markook, also known as Shrak ( Arabic: مرقوق، شراك) is a type of unleavened flatbread common in the countries of the Levant. It is baked on a domed or convex metal griddle, known as saj. It is usually large, about 2 feet in diameter, and thin, almost translucent. Similar to the procedures for making some other flatbreads, the dough of markook is flattened and kept very thin before cooking, resulting in a very slender depth. It is usually folded and put in bags before being sold. It is commonly compared to pita bread, which is known in Mediterranean cuisine.
