Boiling Pearls

Bubble tea is remarkably difficult to prepare. For one, I never seem to get that syrup-tea mix up to the optimal levels. Moreover, every time I boil the tapioca balls, weird things happen when I store 'em. They clumped in the bowl despite my soaking them in water first. Worse yet, they became hard on the inside instead of chewy like they were when freshly boiled. I suspect it's something to do with keeping them in the fridge instead of leaving them in the open.
