Ghee is a Sanskrit word for a clarified butter used primarily in Indian cuisine. Because the preparation of ghee involves heat, it has a distinctive toasted flavor, often described as nutty. Before the advent of commercial vegetable oils, ghee was widely used for deep frying. Unlike other butter-based products, ghee has a high smoking point and can be stored without refrigeration for weeks. As long as ghee is stored in air-tight containers, it does not spoil easily.

Traditional ghee is produced from the milk of buffalo indigenous to the regions of India and Pakistan, but it can also be made from any other milk-producing animal. The process begins with the standard butter created through the churning of milk fats, solids and water. This butter still contains a significant amount of moisture, which must be boiled off to create a clarified butter.
Sticks of pure butter are placed in a large saucepan or kettle over medium to high heat. As the butter melts, it begins to boil. The solids settle to the bottom, while a thicker layer of oil forms in the center. The excess water forms a foamy top layer as it boils away.
