Yesterday at the market I was browsing the fruit juices, and another foreigner walked up and grabbed this orange drink and said "this is the best one" so I thought ok, I'll give it a try. Then I looked at the label and saw "WITH ORANGE SACS" ???
This morning I popped it open, still curious as to what orange sacs really are, and took a sip. Ah ha! It's like drinking a can of diced up tangerines, so delish.
