Way to cook sea fish (small ones) (4-3)
I believe the answer is:
deep-fry
'way to cook' is the definition.
(I know that deep-fry is a more specific form of the action fry)
'sea fish small ones' is the wordplay.
'sea fish' becomes 'deep' (I can't justify this - if you can you should believe this answer much more).
'small ones' becomes 'fry' (I've seen this in another clue).
'deep'+'fry'='DEEP-FRY'
Can you help me to learn more?
(Other definitions for deep-fry that I've seen before include "Cook (chips etc)" , "Cook in oil" , "Fed pyre (anag.)" .)
