Name the gentleman that sent back the dish (7)
I believe the answer is:
risotto
'dish' is the definition.
(risotto is a kind of dish)
'name the gentleman that sent back' is the wordplay.
'name' becomes 'otto' (Otto is an example).
'the gentleman' becomes 'sir' (a man may be addressed as sir).
'that sent back' is a reversal indicator.
'otto'+'sir'='ottosir'
'ottosir' backwards is 'RISOTTO'.
'the' is the link.
(Other definitions for risotto that I've seen before include "It has roots in Italian rice-based dish" , "Italian food" , "Savoury rice dish" , "food dish" , "Rice/stock dish" .)
