Cook this dish and enjoy it, and you may actually feel like royalty yourselfThis recipe calls for ghee, an ingredient that originated in india. Ghee is basically clarified butter that is taken one step further. After the milk solids have separated from the liquid, the mixture is simmered until all of the liquid has evaporated and the solids have started to turn brown in color. The resulting butter has a very high smoke point, making it ideal for frying. Ghee brings a caramel-like, nutty flavor to a dish. It can be expensive but is worth the splurge for special occasion dishes like this one. You can find ghee in indian and middle eastern markets.
