Wash and soak 1/2 cup of Basmati rice in water for 30 minutes.
Drain the soaked rice and grind it into a coarse paste.
Heat 1 liter of full-fat milk in a heavy-bottomed pan until it boils.
Reduce the flame and slowly add the rice paste to the milk.
Now, allow the mixture to thicken. It takes 20-25 mins.
Add 1/2 cup of sugar, 1/4 teaspoon cardamom powder and saffron strands.
Now, let the phirni cool slightly.
Transfer the phirni into serving bowls.
Garnish with chopped nuts and rose petals (optional).
Refrigerate for a few hours and voila.
