Keep on collecting the cream of milk in a container, preferably a glass container. The cream shown above in pictures is collected over 7-10 days. You should store the collected milk cream in fridge to ensure that it does not get spoiled. You will get thick milk cream, if you boil milk and refrigerate overnight. In the morning you will get thick milk cream. The milk cream collected over time will start separating from the water. Water will go to the bottom and cream will be on top.
Transfer the entire contents of the container, i.e. the collected milk cream in a food processor. Fix the blade used to churn milk and keep it on speed 1 for 5 minutes.
You will observe that the butter has separated from the milky water or whey. The milky water is known as whey or buttermilk and the solidified part is butter.
Transfer only the butter in a deep bottom pan. Preferably an hard anodized pan or a non-stick pan.
Retain a little buttermilk. Wash the container and transfer the buttermilk into it.
Now keep the container in which butter is present on the gas or stove. Keep it on medium heat.
The butter will start melting.
Soon you will see clear bubbles forming. Now lower the heat.
Heat it little more till you see clear ghee on top. Now switch off the gas. Don't worry if milk solids burn. Discard it later. Pass the ghee through a strainer or filter and collect the pure ghee in a clean container. I collect this in glass container as I love it that way.
Notice that you got pure ghee now. You can smell it and enjoy the aroma of the ghee.
