It's not milk in a lot of cases but non-dairy creamer. After all if a large percentage of your target audience is lactose intolerant would you be using dairy? Taro flavor is probably my favorite although the color can be somewhat alarming to inexperienced individuals.

I'm not sure how the OP ended up with chocolate boba as that usually requires a special request vs. ending up with the standard variety which is really mostly tasteless.

Oh well, more for the rest of us!
