Sweet little things found in harem perhaps (8)
I believe the answer is:
sultanas
This clue is a double definition.
'sweet little things' is the first definition.
(small raisins)
'found in harem perhaps' is the second definition.
(historically a harem might have included sultanas)
(Other definitions for sultanas that I've seen before include "Currants" , "concubines" , "Dried seedless grapes" , "Dried fruit - female relatives of a Muslim ruler" .)
