How is butter tea prepared in Tibetan culture?

In Tibetan culture, butter tea is a traditional and essential beverage prepared through a specific process. To make it, brick tea—often sourced from other parts of China—or local Tibetan tea leaves are first boiled in soda water.1

Once boiled, the tea is strained and poured into a churn. Salt and butter are then added to the liquid, and the mixture is thoroughly churned together. The final result is a beverage that is light reddish-white in color, characterized by a thick, buttery surface. This tea is a staple of the Tibetan diet, which also includes barley flour and yak meat.12
