It's supposed to be the Chinese equivalent of candy floss, but it's nothing like it. It comes in solid blocks that are crumbly and taste of a mixture of peanuts and sesame; there's supposed to be some coconut in them, too, but (fortunately) I couldn't taste any of that in the ones I tried.
So far, I've eaten three of them. They suck the moisture right out of the mouth. I've had to drink something to get them to break down enough that I could swallow them.
Either:
I'm eating them wrongly.
Something happened to them during transit and they're not how they should be.
They're meant to suck the moisture out of your mouth.
Hmm, I could use the ones I have remaining to write on walls.
