The most characteristic and ancient element of Greek cuisine is olive oil, which is used in most dishes. It is produced from the olive trees prominent throughout the region, and adds to the distinctive taste of Greek food. The olives themselves are also widely eaten. The basic grain in Greece is wheat, though barley is also grown. Important vegetables include tomato, aubergine(eggplant), potato, green beans, okra, green peppers, and onions. Honey in Greece is mainly honey from the nectar of fruit trees and citrus trees: lemon, orange, bigarade (bitter orange) trees, thyme honey, and pine honey. Mastic (aromatic, ivory-coloured resin) is grown on the Aegean island of Chios.

Greek cuisine uses some flavorings more often than other Mediterranean cuisines do, namely oregano, mint, garlic, onion, dill and bay laurel leaves. Other common herbs and spices include basil, thyme and fennel seed. Parsley is also used as a garnish on some dishes. Many Greek recipes, especially in the northern parts of the country, use “sweet” spices in combination with meat, for example cinnamon, allspice and cloves in stews.

The climate and terrain has tended to favour the breeding of goats and sheep over cattle, and thus beef dishes are uncommon. Fish dishes are common in coastal regions and on the islands. A great variety of cheese types are used in Greek cuisine, including Feta, Kasseri, Kefalotyri, Graviera, Anthotyros, Manouri, Metsovone, Ladotyri (cheese with olive oil), Kalathaki (a specialty from the island of Limnos), Katiki-Tsalafouti (both creamy cheeses, suitable for spreads) and Mizithra.

Too much refinement is generally considered to be against the hearty spirit of the Greek cuisine, though recent trends among Greek culinary circles tend to favour a somewhat more refined approach.

Dining out is common in Greece, and has been for quite some time. The Taverna and Estiatorio are widespread, serving home cooking at affordable prices to both locals and tourists. Recently, fast food has become more widespread, with local chains such as Goody’s springing up, though most McDonald’s have closed.[9] Locals still largely eat Greek cuisine.[10] In addition, some traditional Greek foods, especially souvlaki, gyros, pita such as tyropita and spanakopita (respectively, cheese and spinach pie) are often served in fast food style.

Greek cuisine has a culinary tradition of some 4,000 years and is a part of the history and the culture of Greece. Its flavors change with the season and its geography.[2] Greek cookery, historically a forerunner of Western cuisine, spread its culinary influence, via ancient Rome, throughout Europe and beyond.[3] It has influences from the different people’s cuisine the Greeks have interacted with over the centuries, as evidenced by several types of sweets and cooked foods.

Ancient Greek cuisine was characterized by its frugality and was founded on the “Mediterranean triad”: wheat, olive oil, and wine, with meat being rarely eaten and fish being more common.[4] This trend in Greek diet continued in Roman and Ottomantimes and changed only fairly recently when technological progress has made meat more available. Wine and olive oil have always been a central part of it and the spread of grapes and olive trees in the Mediterranean and further afield is correlated with Greek colonization.[5][6]

Byzantine cuisine was similar to the classical cuisine, with the addition of new ingredients, such as caviar, nutmeg and basil. Lemons, prominent in Greek cuisine and introduced in the second century, were used medicinally before being incorporated into the diet. Fish continued to be an integral part of the diet for coastal dwellers. Culinary advice was influenced by the theory of humors, first put forth by the ancient Greek doctor Claudius Aelius Galenus.[7] Byzantine cuisine benefited from Constantinople’s position as a global hub of the spice trade.[8]

Greece has an ancient culinary tradition dating back several millennia, and over the centuries Greek cuisine has evolved and absorbed numerous influences and influenced many cuisines itself.

Some dishes can be traced back to ancient Greece: lentil soup, fasolada, retsina (white or rosé wine flavored with pine resin) and pasteli (candy bar with sesame seeds baked with honey); some to the Hellenistic and Roman periods: loukaniko (dried pork sausage); and Byzantium: feta cheese, avgotaraho (cured fish roe) and paximadi (traditional hard bread baked from wheat, barley and rye). There are also many ancient and Byzantine dishes which are no longer consumed: porridge as the main staple, fish sauce, and salt water mixed into wine.

Many dishes entered Ottoman dishes from the Levant and other near-eastern staples are traditional Greek cuisine staples especially these that came to prominence and as broader consumption in Ottoman cuisine namely: moussaka, tzatziki, yuvarlakia, keftethes, boureki, and more.

The Ottoman Empire having its origins from pastoral nomads in the Eurasian and middle eastern steppe, were largely consigned to diets of minced meats and cheeses with little to no grain as evident with Adana style kofta and other traditionally Turkish staples from the Eurasian steppe.
