Pour the cream in a large bowl and beat it using an electric beater till you can see white liquid in the bowl. It took me 20 minutes to get to this stage. Note : The stages to get to this stage is, first the cream got soft peaks, then stiff peaks, then the cream started turning a little yellow and then it gave out white liquid.
This white liquid is buttermilk and can be used to prepare bread etc. Pour the buttermilk into another bowl
This is our butter. But the butter might have some buttermilk left and if we do not remove all the buttermilk from the butter, the butter will go bad if not used within 2-3 days.
In order to remove the buttermilk from the butter completely, add ice cubes in water to get ice cold water and pour 4 tbsp of this water on the butter and beat it again for 3-4 minutes and we will get white liquid. Discard the water. Repeat this process till we get clear water.
Place the butter on a plastic wrap and roll to get a tight tube.
Place in fridge for 1-2 hours and can use as required.
