Fool with yellow Caribbean dish (4)
I believe the answer is:
jerk
'fool' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for jerk that I've seen before include "Abrupt movement" , "fool" , "Twitch" , "Pull suddenly - twerp!" , "preserved beef" .)
