Yesterday, I had my first bubble drink since... I guess it was five months ago; that is so long for a bubble tea fix. I had (yesterday) a passion fruit smoothie with tapioca pearls; my wife had black tea with papaya flavor and tapioca pearls... it was a minute of blissful heaven.
You can make your own, which is always a healthier and better (depending on your effort and the materials you use). Like I said, bubble teas are essentially smoothies with (or without tea) with tapioca pearls (WuFuYuan - Tapioca Pearl (Black) - Net Wt. 8.8 Oz.
My favorite flavors are, passion fruit (smoothie), taro (smoothie), green tea (without or with passion fruit or lychee juice) and cream (hot and cold), and honeydew melon (smoothie).
