Preparation :
Flake kadayif and place on a shallow cake pan, sprinkle crushed walnuts over evenly and spread the other half of the kadayif on top. Sprinkle melted margarine over and place in moderate oven to bake for 40 minutes.
SYRUP: Meanwhile, put the granulated sugar, the water and lemon juice into a saucepan and boil until moderately thick. When golden brown, take kadayif out of oven and sprinkle boiling syrup over immediately. Cover and allow to cool. When cool, place a plate large enough over the top of the pan and transfer kadayif onto the plate by turningit upside down.
