HOW TO SIP BUTTER TEA
Butter tea is made from tea leaves, yak butter, water and salt. Also known as po cha (Tibetan tea), cha suma (churned tea) or suyoucha in Mandarin.
Because butter is the main ingredient, butter tea provides plenty of caloric energy and is particularly suited to high altitudes. The butter also may help prevent chapped lips.
Butter tea is consumed in separate sips, and after each sip, the host refills the bowl to the brim. Thus, the guest never drains his bowl.
If a visitor does not wish to drink, the best thing to do is to leave the tea untouched until the time comes to leave, and then drain the bowl. In this way, etiquette is observed, and the host will not be offended.
Butter tea is also poured on tsampa (roasted barley flour), or the tsampa is dipped into it.
