Dished up again, possibly cold (8)
I believe the answer is:
reserved
I believe this clue is a double definition.
'dished up again possibly' is the first definition.
(as in serving up food again)
'cold' is the second definition.
(thesaurus)
(Other definitions for reserved that I've seen before include "Slow to reveal emotion" , "Slow to reveal opinions; kept by" , "Spoken for" , "Booked - reticent" , "Bashful" .)
