Heaven in a glass for anyone who can’t get enough of Parle-G. Make the milkshake by adding milk, toffee sauce, ice cream and ice cubes in a blender. To make the Parle-G pebbles, break Parle-G biscuits into small pieces and add liquid nitrogen on it until they are completely frozen. Blend them until thick. Serve the milkshake in a tall glass and top it up with lots of Parle-G Pebbles and whipped cream.
