First boil the milk and cool down completely. Then add a cup of milk in a grinding jar. Crumble the leftover pedas and add it too. In it add the liquid glucose and cardamom powder at the same time. You can even add the cardamom powder later. Now grind everything into a smooth paste as shown below.

Now add this mixture in a big pan and add the remaining milk too. Now let it come to boil. Then add crushed cashews and rose water. Now boil it for another 10 minutes until it reduces to 3/4th. Switch off the flame.

Let the mixture cool down completely. Now pour the mixture into the kulfi mould and let it set for about 8 hours or overnight. Then demould and enjoy them next day.
