Grind together sugar, almonds, pistachios, saffron and cardamom together to a slightly coarse mixture, set aside.
Boil milk in a pan. Simmer for 15 mins till milk reduces. Stir in between to avoid burning at the bottom.
Now add nuts sugar mixture.
Add khoya and cook for few more mins. Malai will start collecting.
Scrap the sides and keep cooking till the mixture is thick and creamy.
Keep cooking till it coats the ladle as shown. Cool down completely. Then pour it in kulfi moulds / popsicle moulds…I used my kulfi shaped popsicle moulds.
Wrap with silver foil, insert ice cream stick and freeze for 6-8 hours at least, I always freeze it overnight.
Then show the popsicles side part under running tap water. Slowly remove the kulfis and serve.
Serve Thandai Kulfi immediately.
