JW asked for bubble tea recipes -- here are a few:
* Bubble tea history and recipe -- "The drink originally started as a childhood treat in Taiwan in the late 1980's at small tea stands in front of the schoolhouses."
* Another bubble tea recipe
I've never tried to make my own bubble tea, but it doesn't look too hard. Just need to hunt down a store that sells large tapioca pearls...they must be sold somewhere in Germany.
