Cold Indian potato fine (5)
I believe the answer is:
aloof
'cold' is the definition.
(synonyms)
'indian potato fine' is the wordplay.
'indian potato' becomes 'aloo' (I've seen this before).
'fine' becomes 'f' (abbreviation).
'aloo'+'f'='ALOOF'
(Other definitions for aloof that I've seen before include "Remote, distant" , "Standoffish like a fool" , "Indifferent - by oneself" , "Coldly distant" , "Unpleasantly cold" .)
