My son has an allergy to casein,the protein in milk. I have spoken to the owner of Purity Farms, a major ghee company in Denver, and they *claim* that there is no protein left in ghee, only milkfats. I did not ask about lactose, and I am curious if anyone else has checked on ghee's content. For those not familiar with ghee, it is clarified butter (also used in some French cooking). Ordinary butter is heated to boiling, and certain residues rise to the top, and are skimmed off. Other residues sink to the bottom and are discarded. The remainder has a long shelf life without refrigeration. Bill Elkus
