The area has climates suited for the cultivation of apples, but pears, peaches, quince and figs are also grown.
en.wikipedia.org Because of the colour and taste, quinces are often pressed along with the apples.
en.wikipedia.org The resulting stewed quince, called "muraba" is then preserved in jars and eaten like jam.
en.wikipedia.org Pears are the most susceptible, but apples, loquat, crabapples, quinces, hawthorn, cotoneaster, pyracantha, raspberry and some other rosaceous plants are also vulnerable.
en.wikipedia.org Some varieties however are not compatible with quince, and these require double working.
