For the uninitiated, Q Q isn't just a sad face emoticon, but is actually also a descriptor for food here in Taiwan (and I imagine in some other Asian countries, but possibly not...)
You'll often see people touting their food as being "Q", which a lot of people seem to like here.
But what exactly is Q? Apparently, it means chewy...but in a nice way. Some sort of medium between al dente and chewy. Things like mochi, well cooked noodles and good pearl milk tea pearls are all Q.
The more you know!
