How to Make clarified butter ghee

In this video Lori Winders shows us how to make ghee from regular butter. Her method takes about two hours to complete but she says that this way you can obtain much more ghee at one time. First, put two pounds of butter in a large cast iron skillet and then put it in the oven at a temperature of 250 degrees for two hours. After this is complete you take the pan out of the oven and with the help of a strainer and lots of layers of cheesecloth you filter the obtained gee in a jar. You will see the jar filling up with a yellow liquid but when it will come to room temperature it will solidify and you will have a smooth and mellow gee.
