Clarified butter or ready-to-use ghee can be purchased in most grocery stores. You can also prepare it at home. In a saucepan, melt 1 lb of butter and simmer for at least 20 minutes, skimming regularly. Pour the butter into a strainer; the remaining liquid is the ghee. It can be stored for several months in the refrigerator. Unlike traditional melted butter, ghee does not burn.
