Master race destroyed elite (5)
I believe the answer is:
cream
'elite' is the definition.
(cream is a kind of elite)
'master race destroyed' is the wordplay.
'master' becomes 'm'.
'destroyed' indicates anagramming the letters.
'm'+'race'='mrace'
'mrace' is an anagram of 'CREAM'.
(Other definitions for cream that I've seen before include "Best part of the milk" , "Top or best part" , "Very best; pale yellow" , "Best - ointment" , "An off-white shade" .)
