Dish to stir, mixing round (7)
I believe the answer is:
risotto
'dish' is the definition.
(risotto is a kind of dish)
'to stir mixing round' is the wordplay.
'mixing' indicates anagramming the letters.
'round' becomes 'o' (round can mean a round object).
'to'+'stir'='tostir'
'tostir' with letters rearranged gives 'risott'.
'risott'+'o'='RISOTTO'
(Other definitions for risotto that I've seen before include "F" , "dishy thing!" , "Italian course" , "Perhaps Italian" , "It has roots in Italian rice-based dish" .)
