Hello foodie friends... Today I am going to share recipe of Bulletproof Coffee. Yes but not any connection with Bullet. Generally it's famous and taken by people of Tibbat, some area of Himalaya region and Nepal. Also famous in some area of China. They use yak's milk butter. Because it's provide them energy to walk and climb on hills. Previous it known as Butter coffee but Asprey developed his Bulletproof Coffee recipe after traveling to Tibet and tasting yak-butter tea drinks.He returned to the United States and experimented with buttered drink recipes and published the preparation for his buttered coffee drink on his blog in 2009.
