In that video, the woman showed how to make ghee very simply. Making ghee is not a one-day process. Every day we store the cream from the milk or the curd. After ten days, we mix it all together. The woman in this video did the same. However, she did it very simply.
She took all the cream she had stored in a bowl. She waited for it to come to normal temperature. After that, she put all the cream in a cooker and added some water to it. After that, she closed the cooker lid and let out one whistle. That's it. After that, she removed the whistle and poured it into another bowl and put it on the stove and boiled it for five minutes.
