Looking red as a fine meal ruined (6)
I believe the answer is:
aflame
'looking red' is the definition.
(on fire)
'a fine meal ruined' is the wordplay.
'fine' becomes 'f' (abbreviation).
'ruined' indicates an anagram.
'meal' is an anagram of 'lame'.
'a'+'f'+'lame'='AFLAME'
'as' acts as a link.
(Other definitions for aflame that I've seen before include "Ablaze" , "Ardent" , "Indicating excitement" , "Deeply aroused" , "On fire" .)
