Bulletproof Coffee

Thanks ANON, made me laugh.
It sounds like a trendy rough copy of the Mustang Coffee [named after the place at about 29° N, 84° E] I drank years back, whilst walking a few hills some distance away.
To make Mustang Coffee; A good measure of coffee, a little hot hot water and local rum to almost the brim of the mug and top off with a knob of Yaks' butter, preferably slightly rancid.
That will see you through a few hours of cold.
