The best made coffee has a nice little thick bubbly layer on top, called wissh (or face in English). You can put a few drops of cold water into this with your finger - I am not sure why this is done, but I think it has something to do with getting the grains to settle at the bottom.
Be careful, do not drink the cup to the bottom! Leave the grains behind!
Interesting facts:
- in Albania they drink the same coffee but with milk
- if you get tummy troubles while traveling in Egypt, be sure to ask for a cup of Turkish coffee prepared with lemon - all of the Nile cruises are well acquainted with this natural remedy.
- Egyptian fortune-telling is done by turning the remains of a clear glass of coffee cup upside down and reading the patterns in the grains.
