Hong Kong’s famous milk-tea, a Chinese-South Asian derivative of British tea, includes boiling the tea with egg-shells and dried dates, and filtering it while pouring it back and forth (for aeration) through a woman’s stocking (preferably not used...)
with condensed milk and sugar added.
Sounds like a lot of work.
Costco has something called Boba Milk Tea Mochi. I had no idea what it was but decided to try it. I ate all of them..but then again..I even managed to get down that Tan Hue Vien Banh Pia Hopia Cake with Durian. If I paid for it I am going to eat it...but I had to freeze those to eat them.
