Thoroughly wash 1/2 cup Basmati Rice 3-4 times with water. Soak in water for 30 mins.
Add 1 liter (34 oz) whole milk and 1/2 cup heavy cream to a pan. Heat on high heat, stir occasionally to ensure it doesn’t stick to the bottom of the pan. Bring it to a boil.
Reduce heat to medium. Add 1/4 cup thandai masala, soaked rice without the water. Cook for 25-30 mins until milk is reduced and rice is cooked. Add more milk to adjust consistency if needed.
Add 2/3 cup powdered sugar. Add more if needed as per your liking. Mix well and remove from heat.
Serve hot or cold. Garnish with chopped cashews, pistachios, rose petals and enjoy
