For the syrup :
Place 1 pastry sheet in well-buttered 9 X 13 inch baking pan and brush with butter. Place second pastry sheet on top of the first and butter again. Repeat until 6 layers of buttered pastry sheets have been built up. Mix walnuts or almonds, breadcrumbs, sugar, cinnamon and cloves. Sprinkle top pastry sheet with a thick layer of walnut mixture and place two buttered pastry sheets over this. Repeat in same manner until all ingredients have been used, ending with 6 pastry sheets. Brush top with remaining butter and trim edges with sharp knife. Cut diagonal lines over the length of the pan to make diamond-shaped pieces. Sprinkle with water. Bake in a moderate oven for about 1 hour until golden.
Boil sugar, water and lemon juice for 10 minutes. Pour the syrup over the baked baklava after it cools. Wait a few hours to serve. Makes 30 servings.
