Riding high on my minor successes with Hong Kong milk tea (and discovering someone who sells shelf-stable yak ghee), I thought I'd try another boiled tea, Tibetan butter tea.
Bought some young, dry-stored 2018 Dayi tuo-chas from their Amazon store (anyone know what the story is behind this? I suppose it could be a fake store, but the selection seems a little odd for that), and tried to see if I could make do without a butter churn.
Yak butter tastes more like cheese than butter. If I had to pick, I'd say "oil of Parmesan" might be a good description.
I think that ghee is maybe too clarified, though, as it melts clear, so you don't get that milky look. I tried to work around this by adding a little evaporated milk, but this might be the wrong direction. Maybe the churning emulsifies the butter with the tea somehow?
Another thing that helped was that you are supposed to add some soda or potash to the water you make the tea in, sort of like with Kashmiri Chai, which sort of replicates making tea in hard water, making it not quite so harsh as a young green boiled sheng in soft water would be.
Boiled the tea for around 15 minutes, gave it a good aeration, warmed it back up, poured it on some yak ghee while whisking quickly, then stirred in some evaporated milk.
Drinkable, and no obvious ill-effects, which are both good signs.
