Cake ingredient for ruler’s wife (7)
I believe the answer is:
sultana
'cake ingredient' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'ruler's wife' is the wordplay.
I cannot really understand how this works, but
'ruler' could be 'sultan' (sultan is a kind of ruler) and 'sultan' is located in the answer.
A single letter 'a' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for sultana that I've seen before include "Grape; ruler's wife" , "bit of a fruit cake" , "Shrivelled up" , "mistress abroad" , "sovereign's woman" .)
