Reminds me of yak butter. I went to an IMAX movie about Mt. Everest. It was filmed at the time that group got caught in that freak snowstorm and so many died. Well, one of the guides, when he got back to his village, was so grateful that he survived that he held a religious ceremony of some kind and had hundreds of yak butter lamps burning.
Yak butter.
