Seedless raisins (8)
I believe the answer is:
sultanas
'seedless raisins' is the definition.
('sultana' can be a synonym of 'seedless raisin')
This is the entire clue.
(Other definitions for sultanas that I've seen before include "concubines" , "Dried fruit - female relatives of a Muslim ruler" , "Currants" , "Dried seedless grapes" .)
