When I cooked something like beef or grouse (5)
I believe the answer is:
whine
'something like beef or grouse' is the definition.
I can't judge whether this definition defines the answer.
'when i cooked' is the wordplay.
'cooked' indicates anagramming the letters (letters cooked into a new form).
'when'+'i'='wheni'
'wheni' with letters rearranged gives 'WHINE'.
Can you help me to learn more?
(Other definitions for whine that I've seen before include "Gripe" , "Complaining cry" , "Shrill sound of dog" , "Nagging complaint" , "Whimper" .)
