Turkish & Greek cuisine is largely the heritage of Ottoman cuisine, which can be described as a fusion and refinement of Central Asian, Middle Eastern, Mediterranean and Balkan cuisines. Turkish & Greek cuisine has in turn influenced those and other neighbouring cuisines, including those of Western Europe. The Ottomans fused various culinary traditions of their realm with influences from Middle Eastern cuisines, along with traditional Turkic elements from Central Asia (such as yogurt), creating a vast array of specialities - many with strong regional associations. Turkish & Greek cuisine varies across the countries. The cooking of Istanbul, Bursa, Izmir, and rest of the Aegean region inherits many elements of Ottoman court cuisine, with a lighter use of spices, a preference for rice over bulgur, koftes and a wider availability of vegetables staw turlu, eggplant, stuffed dolmas and fish. The cuisine of the Black Sea Region uses fish extensively, especially the Black Sea anchovy, has been influenced by Balkan and Slavic cuisine, and includes maize dishes. The cuisine of the southeast—Urfa, Gaziantep and Adana—is famous for its kebabs, mezes and dough-based desserts such as baklava, kadayıf and künefe. Especially in the western parts of Turkey, where olive trees grow abundantly, olive oil is the major type of oil used for cooking. The cuisines of the Aegean, Marmara and Mediterranean regions are rich in vegetables, herbs, and fish. Central Anatolia has many famous specialties, such as keşkek (kashkak), mantı (especially from Kayseri) and gözleme. A specialty's name sometimes includes that of a city or region, either in or outside of Turkey, and may refer to the specific technique or ingredients used in that area. For example, the difference between urfa kebab and adana kebab is the thickness of the skewer and the amount of hot pepper that kebab contains. Urfa kebab is less spicy and thicker than adana kebab.
