Wanting to find out what the fuss was all about, I press-ganged my JK daughter and went to Gong Cha, one of the biggest and most famous Taiwanese tea cafes with 1300 branches worldwide. Ordering itself is quite an ordeal in itself (at least for this old codger): you have to choose (1) size and type of tea (jasmine green, oolong, and black are the staples) either hot or iced, (2) sweetness (amount of syrup), (3) amount of ice (if you chose iced), and (4) up to three toppings (which as well as the obligatory tapioca pearls, also include milk foam, aloe, nata de coco=coconut gel, basil seeds, and grass jelly).
I ordered medium hot jasmine-green tea with just a little syrup and pearls and milk foam for topping (I think) and joined the pick up queue, much like Starbucks. Ordering hot is not very cool apparently because the cup is not transparent thereby losing the chance for a good instammagrable snap showing the black tapioca balls floating in the bottom of the tea. The jasmine/green-tea blend was quite refreshing and the chewiness of the pearls rather unique at first though after sucking up what seemed like a never-ending stream of the things I was feeling quite full and wishing I had ordered a small size. Part of the reason for this may be that tapioca has a negative image for generations of British school children: tapioca pudding ("frog spawn") was a school lunch staple that has been named Britain's most hated school pudding. The Japanese, on the other hand, seem quite enamoured by the chewiness (described as mochimochi-kan in Japanese) which is perhaps not surprising given that the texture is very similar to that other popular Japanese jaw-breaker, mochi or rice-cake, which I covered only very recently in this blog.
But be warned, there's a darker side to the bubble tea boom. A Chinese teenager addicted to the drink was apparently rushed in agony to hospital where they found more than 100 bubble tea pearls stuck to her digestive tract! See here for a Japanese article and here for a short video with some scary x-ray pics. The moral here: chew your tapioca balls slowly if you want to avoid constipation and hospitalisation!
