Preparations such as jam, ice cream and desserts, and even sauces for fish preparations, based on the distinctively flavored resin of the tree "pistachia lentiscus" from which it is harvested, are among nationally known culinary specialties of Çeşme. The adjacent Greek island of Chios (sakız in Turkish is the name for both Chios and mastic resin) is the source of mastic resin. Some efforts to produce mastic resin (in Greek mastiche, μαστίχη) in Çeşme, where climate conditions are similar, but they failed to produce the aromatic mastiche. A number of efforts are being made to rehabilitate the potential presented by the mastic trees that presently grow in the wilderness, and to increase the number of cultivated trees, especially those planted by secondary-residence owners who grow them as a hobby activity. The fish is also abundant both in variety and quantity along Çeşme district's coastline.
