Sweet liquid Cretan stirred (6)
I believe the answer is:
nectar
'sweet liquid' is the definition.
(I've seen this before)
'cretan stirred' is the wordplay.
'stirred' indicates anagramming the letters.
'cretan' is an anagram of 'NECTAR'.
(Other definitions for nectar that I've seen before include "That's sweet" , "Sweet floral secretion" , "juicy material" , "Sweet fluid produced by flowers" , "very nice drink" .)
