Take a pinch of Saffron and grind it into a fine powder using a pestle and mortar or electric grinder. Brew it on indirect heat. Meanwhile, pour water, sugar, cardamom, and rose water into a bowl and bring to a boil over medium heat. After the syrup reaches the desired concentration, add the brewed saffron. Let the syrup boil for a few more minutes. You can keep the tasty syrup in the fridge.
