Indian potato following is rather cold (5)
I believe the answer is:
aloof
'rather cold' is the definition.
(I've seen this before)
'indian potato following' is the wordplay.
'indian potato' becomes 'aloo' (I've seen this before).
'following' becomes 'f.' (used when citing page numbers etc).
'aloo'+'f'='ALOOF'
'is' is the link.
(Other definitions for aloof that I've seen before include "Cool, distant" , "Unapproachable, distant" , "Unpleasantly cold" , "Snooty" , "Indifferent - by oneself" .)
