Probably best to try some, buy some acorn flour from K-Mart, to see whether it’s worth the effort.
In my experience, Koreans kinda it, most other people trying it do not.
Also you need Olympic level chopstick skills to actually eat the cold, wriggly, slimy slabs of sadness.
Perhaps we should gather some Ruislip acorns, this Autumn, and make some dotorimuk?
