Make sure your fridge is in good condition.
Store the collected cream inside the FREEZER, nowhere else. If you want to collect the cream soon after boiling the milk, make sure the cream cools down, before you close the lid of the container and store it back to the freezer.
To get the maximum amount of cream, after boiling the milk, keep it in the refrigerator once cooled, for an hour or more. Take it out of the fridge, you will see cream or ‘malai’ as called in Hindi, floating on top of the milk. Separate and collect it.
Use ICE COLD water for making butter. If you want to make butter out of store bought cream, keep the packet in the fridge for few hours, before proceeding further. No need to add water.
