Ghee is a class of clarified butter that is commonly used in South Asian and Arabic cuisines. Ghee is prepared by simmering butter, skimming any impurities from the surface, and then pouring and retaining the clear, still liquid fat, while discarding the solid residue that settled on the bottom. Spices can be added for flavour. The texture, colour, and taste of ghee depend on the quality of the butter, the source of the milk used in the process and the duration of the boiling.
