It's actually ghee, but we think whee sounds a lot more fun.

Ghee is really a more refined form of clarified butter, in which the butter is heated until all the water evaporates and the milk solids brown before being removed. It has a darker color than clarified butter, a higher smoke point, and a nuttier flavor one associates with browned butter.

Some of the bottled products sold in this country as ghee, however, appear to have omitted the browning step, so they are little more than clarified butter.
