Stew one has to stir round perhaps (7)
I believe the answer is:
risotto
'stew one' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe there's an association between them I don't understand?
'to stir round perhaps' is the wordplay.
'round' indicates anagramming the letters.
'perhaps' becomes 'o' (I can't justify this - if you can you should believe this answer much more).
'to'+'stir'='tostir'
'tostir' with letters rearranged gives 'risott'.
'risott'+'o'='RISOTTO'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for risotto that I've seen before include "scoff" , "food dish" , "Perhaps Italian" , "Italian course" , "You cook it in stock" .)
