Butter Tea, also known as po cha in Tibet, is a creamy, savory tea drink that originated in the Himalayan regions of Nepal, Bhutan, India, and Pakistan.
Typically includes black tea, butter, milk, and salt.
Yak butter tea is smooth and creamy when made with fresh butter, but can taste rancid if the butter is sour. Nomadic people drink butter tea for warmth, energy, and calories
