In a frying pan roast sesame seeds for about 5 minutes on high heat. Pour honey and lemon/orange zest into a large pot and boil for 10 minutes. Let the mixture simmer on lower heat and add the roasted sesame seeds while stirring. When the mixture has thickened remove from heat and let sit (no more than 10 minutes).Line baking pan with non stick paper and sprinkle with rose water or corn oil. Pour mixture slowly and evenly into pan. Use a rolling pin to spread the mixture so there are no holes or gaps.
