Bii)nik Qarma, Anatolia Over hundreds and possibly thousands of years, landraces of wheat, rice, maize and other cultivated grains continually evolved and adapted to their local environment, and were intimately linked to an ecosystem and to a population of people and their culture. This connection In the small Anarolian village of etiyrik Qatma, families had risen at berween plant and place also manifested itself in cooking styles and sunrise and then slaughtered sheep to whispered prayers. The festival recipes, as a feedback loop took place between farmers in fields and of Eid had fallen in late August and husbands and wives worked cooks in kitchens.

Even in harsher years, when winter winds and colder temperarures sweep in early, bere will have grown quickly enough to produce grain when other crops have failed. In good years, modern barley and even whear fed by fertilisers and fungicides yield more than bere, bur in a_.bad year those crops might give nothin g at aJJ. When the weather is rough (and on Orkney it can get very'rough), it's possible to watch bere's resilience in action.
