A cream recipe left some sugar (7)
I believe the answer is:
caramel
'some sugar' is the definition.
(I've seen this before)
'a cream recipe left' is the wordplay.
'recipe' is an anagram indicator.
'left' becomes 'l' (common abbreviation).
'a'+'cream'='acream'
'acream' is an anagram of 'carame'.
'carame'+'l'='CARAMEL'
(Other definitions for caramel that I've seen before include "Chew candy" , "Sugar solution heated till brown" , "It's produced by heating sugar until brown" , "Dark brown substance" , "Burnt sugar used for flavouring" .)
