A cream recipe left sweet (7)
I believe the answer is:
caramel
'sweet' is the definition.
(caramel is a kind of sweet)
'a cream recipe left' is the wordplay.
'recipe' is an anagram indicator.
'left' becomes 'l' (common abbreviation).
'a'+'cream'='acream'
'acream' with letters rearranged gives 'carame'.
'carame'+'l'='CARAMEL'
(Other definitions for caramel that I've seen before include "Toffee-like sweet" , "Soft sweet" , "Browned syrup" , "Cooked sugar" , "Chewy sweet - burnt sugar" .)
