Early historical documents show that the basic structure of the Turkish Cuisine was already established during the Nomadic Period and in the first settled Turkish States of Asia. Culinary attitudes towards meat, dairy, vegetables and grains that characterized this early period still make up the core of Turkish Cuisine. Turks cultivated wheat and used it liberally in several types of leavened and unleavened breads baked in clay ovens, on the griddle, or buried in ember. "Manti" (dumpling), and "bugra" (attributed to Bugra Khan of Turkestan, the ancestor of "börek" or dough with fillings), were already among the much-coveted dishes at this time. Stuffing the pasta, as well as all kinds of vegetables, was also common practice, and still is, as evidenced by dozens of different types of "dolma". Skewering meat as well as other ways of grilling, later known to us as varieties of "kebap" and dairy products such as cheeses and yogurt were convenient and staple foods of the pastoral Turks. They introduced these attitudes and practices to Anatolia in the 11th century. In return they were introduced to rice, the fruits and the vegetables native to the Region, and the hundreds varieties of fish in the three seas surrounding the Anatolian Peninsula. These new and wonderful ingredients were assimilated into the basic Cuisine in the millennia that followed.
