Copper has time for flavouring (5)
I believe the answer is:
cumin
'flavouring' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'copper has time' is the wordplay.
'copper has' becomes 'cu' (I've seen this in other clues).
'time' becomes 'min' (short for minute).
'cu'+'min'='CUMIN'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for cumin that I've seen before include "seasoning" , "Mediterranean plant with aromatic seeds" , "Spice used in chilli and curry powder" , "Aromatic seeds used in cooking" , "relief from wind" .)
