Combine coriander seed, cumin, black pepper, and cardamom seeds (if using) in a mortar and pestle and grind into a powder using a firm, circular motion. Add garlic, chilies, and salt and pound into a rough paste. Add cilantro and parsley one small handful at a time and continue pounding into a rough paste. (By the time you’re done, there should be no pieces of chilies or herbs larger than 1/8 inch remaining.) Pounding constantly, slowly drizzle in olive oil to form an emulsion. Season to taste with more salt. Zhug can be served immediately or stored in an airtight container in the refrigerator for several weeks.

For The Syrup: Prepare the syrup while the kanafeh bakes. In a medium sauce pot, add the sugar, lemon juice, and 1 cup of water. Simmer until the syrup reaches 234°F (112°C), or when a small amount dropped into ice water forms a soft ball. Remove from heat and set aside to cool slightly. When the kanafeh is ready, finish the syrup by adding the rose and orange blossom waters.
To Serve: After removing the kanafeh from the oven, immediately drizzle on about 1/3 of the syrup. Invert the pie onto a serving platter and drizzle with the remaining syrup. Sprinkle with chopped nuts and serve right away.
