For Base
Mix cracker crumbs, ghee or butter, and cardamom powder in a mixing bowl.
Pour the mixture into the 10-inch spring foam baking pan.
Make a tight flat surface by pressing it with a small bowl or cup.
Place it in the freezer to set or until the filling is ready.
For Filling
Pour the yogurt into the cheesecloth or muslin cloth and hang it or press it for 3-4 hours to extract the whey.
Soak the saffron threads in the milk.
Blend the hung yogurt, shredded paneer, heavy whipping cream, sugar, and heavy whipping cream together until smooth.
After heating the saffron milk, add the agar-agar powder and mix well.
Add Thandai masala to the blended mixture and blend again.
Pour the mixture over the prepared base and freeze it for about 4-5 hours or overnight.
The Thandai cheesecake is ready now.
Topping
Mix cream/malai, sugar, and vanilla extract in a bowl. Use a wire whisk and make it light and fluffy.
Fill the whipped cream into a piping bag and top the cheesecake.
Sprinkle some slivered pistachios, almonds, and Thandai masala on top and serve.
