Cow Milk- Lighter color and it varies greatly in taste as compared to Buffalo Milk. The ghee is clarified ( water and milk solid is separated by heat, this results in pure butterfat) and has healthy fats ideal for a balanced diet.

Buffalo Milk : Creamier, darker and richer in texture. The ghee is sourced from Buffalo's Milk and clarified to lend a smooth and coarse texture which lends a warm and nutty flavour to food. However, Buffalo Ghee is higher in fat soluble content such as Vitamin D, E, and K ( stores fat in the fat tissues) in the body for later use.
