Prepare the chai mix: Add the milk, tea, sugar, and spices (if using) in a saucepan Bring the mixture to a boil on high heat, then let it simmer on low heat for 10-15 minutes. Strain the tea and let it chill until ready for use.
300 ml full-fat milk, 8 gs tea leaves, 14 gs sugar, Cardamom pods, Cinnamon stick (or any spices of your choice)
Whip the liquid whipping cream on high speed until they almost reach stiff peaks.
400 gs liquid whipping cream
In another bowl, add the condensed milk and the prepared tea (make sure it’s not hot). Whisk the mixture until everything is well combined.
320 gs condensed milk
Pour the condensed milk mixture into the whipped cream and mix until fully combined. The mixture will be a little liquidy, so chill it in the freezer for 40-50 minutes until it thickens.
Meanwhile, prepare the tray with the Parle-G Biscuits. Place the ice cream back into the freezer for 6-8 hours or overnight. Line the tray with baking paper, and make sure to leave an overhand to make it easy to pick up the ice cream once it's set. Add a layer of Parle G biscuits, face-side down, at the bottom of the tray. (read notes for alternative assembly method)*
3 packets Parle-G biscuits
Once the ice cream has thickened, pour it over the Parle-G layer, set it for another 20 minutes, then cover it with another layer of Parle-G biscuits. Set the ice cream overnight, then remove the ice cream slab from the pan by pulling it up with the baking paper overhang. Cut the sandwiches along the biscuits and serve.
For serving, prepare a cup of chai your way, dip the ice cream sandwiches in the chai and enjoy.
