Fishy ingredient for stuffing
I believe the answer is:
fin
'fishy ingredient for stuffing' is the definition.
I can't judge whether this defines the answer.
'ingredient for stuffing' is the wordplay.
'ingredient' indicates a hidden word (I've seen 'ingredient of' mean this).
'FIN' is hidden in the letters of 'for stuffing'.
Can you help me to learn more?
(Other definitions for fin that I've seen before include "A fish uses it to steer itself" , "Found on a fish" , "For movement and balance in fish" , "Paddle-like organ" , "Fish propeller; end (Fr.)" .)
