Amended moral bias is delectable (9)
I believe the answer is:
ambrosial
'delectable' is the definition.
(thesaurus)
'amended moral bias' is the wordplay.
'amended' indicates an anagram.
'moral'+'bias'='moralbias'
'moralbias' is an anagram of 'AMBROSIAL'.
'is' acts as a link.
(Other definitions for ambrosial that I've seen before include "Divine" , "delicious" , "Like special food" , "Heavenly" , "Delightful" .)
