Like liquorice, the really intense one (salmiak). i don’t think English has a word for it, since it was not recognized as a flavor before.

The thing is, I know the flavor but wouldn’t know how to describe it to someone who doesn’t. Asian (Korean and Chinese, to be precise) friends told me it tasted like medicine to them, because apparently it’s a common flavor in traditional medicine for them?

Edited for typos.
