Ottoman ruler, a sweet little thing (7)

I believe the answer is:

sultana

'sweet little thing' is the definition.
(I've seen this before)

'ottoman ruler a' is the wordplay.
'ottoman ruler' becomes 'sultan' (I've seen this in another clue).
'sultan'+'a'='SULTANA'

(Other definitions for sultana that I've seen before include "Dried pale yellow seedless grape" , "Shrivelled up" , "Queen of fruits?" , "Grape; ruler's wife" , "Dried fruit - Muslim ruler's consort" .)

I've seen this clue in The Everyman puzzle in The Observer.
