Name the gentleman that sent back the dish (7)
I believe the answer is:
Here is my best explanation:
'the dish' is the definition.
(risotto is a kind of dish)
'name the gentleman that sent back' is the subsidiary indication.
'name' becomes 'otto' (Otto is an example**).
'the gentleman' becomes 'sir' (I've seen this before).
'that sent back' is a reversal indicator.
'ottosir' written backwards gives 'risotto'.
(Other definitions for risotto that I've seen before include "Italian course", "F", "scoff", "food dish", "Italian recipe", "dishy thing!", "You cook it in stock", "Food", "Savoury rice dish" and "Rice/stock dish".)
