The creation of this drink (which is popular world-wide) is something that the Taiwanese are very proud of - and rightfully so!
Pearl milk tea is a sweet and refreshing drink consisting of tea, usually black tea, with milk and sugar and chewy tapioca balls, mmmmmmmmmmmm yummy! It might not sound like anything too special but it is definitely a unique and delightful treat. (something which I will truly miss when I move back to the states)
These are in basically every single tea house on the island and they are used to seal plastic lids to to-go cups. Then you just poke a straw through the top and you have the perfect spill-proof drink!
