Returning for Sir Otto, an Italian dish (7)
I believe the answer is:
risotto
'an italian dish' is the definition.
(type of Italian meal)
'returning for sir otto' is the wordplay.
'sir otto' can be anagrammed to 'RISOTTO'.
However, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for risotto that I've seen before include "dishy thing!" , "It has roots in Italian rice-based dish" , "Italian dish cooked with broth" , "You cook it in stock" , "Italian course" .)
