Soak the raisins in half cup water for an hour till soft. Drain and grind into smooth paste.
Pour a cup of water into it and strain the mixture, pressing through to squeeze all flavors.
Add the remaining water, dates syrup, rosewater and sugar to the drained mixture and blitz till well mixed.
Pour into glasses and serve cold with pine nuts topping. Best is to keep it chilled till use.
Notes
If you don't have date syrup, soak around 5 dates along with the raisins and grind along with it. Add sugar and more water depending upon how you want the consistency to be.
