Biscuits not the booze!

Bubble tea cafes are popping up in quite a few places, including the indoor shopping mall in Eastbourne, where I think rents are quite high. So I looked it up - "Bubble Tea, also known as boba milk tea, is a cold, frothy drink made with a tea base shaken with flavors, sweeteners and/or milk with tapioca pearls at the base of the drink. Fat Straw Required. "


None of the ingredients appeal to me at all, least of all tapioca pearls, whatever they are!
