Prepare the syrup first. Put all the ingredients in a small pan and stir until the sugar is dissolved. Put the pan on the hob at a high temperature and do not stir a lot.
Whisk the flour, milk and yeast together and leave aside for 2 hours.
When ready, use a big non-stick pan to cook the katayef.
Sprinkle the bicarbonate soda to the runny dough and mix.
Take 2 big table spoons and pour in the pan in small circles to make a small size Katayef.
Meanwhile, prepare the filling, put the walnuts in a blender, add sugar and rose water, blend until smooth.
Fill each katayef with one spoonful of walnuts and close the 2 sides together making a cone shape.
When ready to serve the katayef sprinkle one teaspoon of syrup, and some Orange blossoms and serve.
You can also deep fry the katayef if you wish and once out sprinkle with the syrup. But you should fold it and stick its sides very well because we do not want to lose our filling in the frying oil.
