...is bubble tea.
The 'pearls' or 'bubbles' in bubble tea are deliciously chewy. They are made of tapioca, which comes from the root of the casava plant. I reckon they look like frog spawn.
I'm fairly 'vanilla' when it comes to bubble tea flavours. So far, I've been ordering mostly plain Oolong tea with the pearls, but I got a bit adventurous today and ordered a milk tea with pearls! Next time, I might even go for a flavoured tea!!
