Choc mixed with gin in dish (7)
I believe the answer is:
gnocchi
'dish' is the definition.
(I've seen this before)
'choc mixed with gin' is the wordplay.
'mixed with' indicates an anagram.
'choc' with its letters anagrammed with 'gin' can make 'GNOCCHI'.
'in' is the link.
(Other definitions for gnocchi that I've seen before include "Italian potato dumplings" , "2 [PASTA]" , "Italian dish" , "Italian dumpling made of potato, flour or semolina" , "Pasta or potato dumplings" .)
