Dri butter

yak butter

Yak butter is butter made from the milk of the domestic yak (Bos grunniens). Many herder communities in China (including Tibet), India, Mongolia, Nepal, and Gilgit-Baltistan Pakistan produce and consume dairy products made from yak's milk, including butter. Whole yak's milk has about twice the fat content of whole cow's milk, producing a butter with a texture closer to cheese. It is a staple food product and trade item for herder communities in south Central Asia and the Tibetan Plateau. Yaks provide their herders with many different benefits, including dung for fuel, draught power, meat, fiber, and milk. Not all herding communities have a tradition of using yak's milk or making butter, although in regions of mountain pastures the practice is common. Each individual yak cow produces little milk, so only when large herds are present can herders expect much milk to be obtained. Milk is much more plentiful in summer than winter; turning fresh milk into butter or cheese is a way to store calories for later use. In western Tibet, yak's milk is first allowed to ferment overnight. In summer, the resulting yogurt-like substance is churned for about an hour by plunging a wooden paddle repeatedly into a tall wooden churn. In winter, yogurt is accumulated for several days, then poured into an inflated sheep's stomach and shaken until butter forms.
