The average Tibetan can drink 50 – 60 cups of this tea in any one day! It is made by drying Chinese tea in the road for several days (to let it acquire a strong flavor). The tea is then boiled for up to half a day and churned in bamboo churns to which salt, a pinch of soda, and rancid butter have been added. When drinking the tea, you can blow the scum (from the butter) away from the edge of the cup and sip. Some Tibetans add “tsu” and flour to their tea (in much the same way as we add milk and sugar). Tsu is a mixture of hardened cheese, butter, and sugar. When you sip the tea, your host will refill your cup as it should always remain full.
