Start by pureeing the Parle G biscuits to a fine powder. Mix with ghee/butter and pack on the base of the cheesecake pan. I recommend using a springform pan. Place in the fridge for 30 minutes.
Mix the paneer, condensed milk and cornstarch together, add to a pan and then top with whipping cream.
Cook the mixture on low heat for 18-20 minutes, stirring frequently. Cool the mixture for 10 minutes and stir in the mango puree.
Pour the paneer mixture over the cookie base and place in the fridge for 4-6 hours or overnight.
This is from the coastal region of Bengal, and you might never have had this classic combination with pickling spices and final finish of fresh ginger.
