Sitcom set in Korea (4)
I believe the answer is:
mash
'sitcom set in korea' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mash that I've seen before include "Brew or infuse (tea)" , "Sausages' traditional partner" , "Sham sort of pulp" , "(Crush into) pulp" , "Reduce to pulp" .)
