Ingredients: 
3 cups rye flour (dura)
1 cup wheat flour
At least one day before mix rye flour with water, adding water until thick paste and cover.  If you want sour kissra, add little wheat flour, for less sour kissra, add more wheat - about 1:3 ratio with rye flour.  Stir in water until thin.
Put a drip of oil on sarge (flat surface for frying, i.e. frying pan) and put small blob of mixture.  Spread thinly with credit card, library card or mobile phone top up card.  Fry for a short time until edges start to lift.  Peal off and stack for later consumption.
