Cold potato flakes (starter only) (5)
I believe the answer is:
aloof
'cold' is the definition.
(both can mean distant)
'potato flakes starter only' is the wordplay.
'potato' becomes 'aloo' (term for potato in Indian cuisine).
'starter only' indicates taking the first letters (I've seen 'starters only' mean this (the letters which start the words)).
The first letter of 'flakes' is 'f'.
'aloo'+'f'='ALOOF'
(Other definitions for aloof that I've seen before include "Remote, distant" , "Coldly distant" , "Cool, distant" , "Displaying supercilious reserve" , "apart from all else" .)
