Something vegetarian from Korea, unusually involving shrimp (9)
I believe the answer is:
artichoke
'something vegetarian' is the definition.
I can't tell whether this definition defines the answer.
'korea unusually involving shrimp' is the wordplay.
'unusually' indicates anagramming the letters.
'involving' means one lot of letters goes inside another.
'shrimp' becomes 'tich' (I can't justify this - if you can you should give a lot more credence to this answer).
'korea' anagrammed gives 'aroke'.
'aroke' enclosing 'tich' is 'ARTICHOKE'.
'from' is the link.
Can you help me to learn more?
(Other definitions for artichoke that I've seen before include "Thistlelike edible flower head" , "Plant with edible flower heads" , "Plant with large edible flower-head" , "Food item" , "Edible thistle-like bud" .)
