Fish like sashimi, say, in wrapping of tinfoil (5)
I believe the answer is:
trawl
'fish' is the definition.
(trawl can mean to fish)
'like sashimi say in wrapping of tinfoil' is the wordplay.
I cannot quite understand how this works, but
'like sashimi' could be 'raw' (I've seen this in another clue) and 'raw' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for trawl that I've seen before include "Net for fishing at sea" , "Drag nets" , "search for a suitable appointment" , "Drag a large net" , "Comb" .)
