What might get put on sweet girl can seem wrong (6,5)
I believe the answer is:
single cream
'what might get put on sweet' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'girl can seem wrong' is the wordplay.
'wrong' is an anagram indicator.
'girl'+'can'+'seem'='girlcanseem'
'girlcanseem' with letters rearranged gives 'SINGLE CREAM'.
Can you help me to learn more?
(Other definitions for single cream that I've seen before include "food" , "Dairy product; cleans grime (anagram)" , "emerges from the dairy" .)
