In your favourite high-powered blender (I recommend Vitamix), add all the ingredients in the order listed. Blend on high for 20-30 seconds. Serve immediately.
Rose water is not mandatory, so feel free to omit if its not your thing. I make my own rose water which is quite subtle, however, you may want to start with a smaller amount if your rose water is particularly strong. Flavour to your liking. I've also enjoyed this smoothie without added honey/sweetener and it's just as good!
