George cooked Cochin dumplings? (7)
I believe the answer is:
gnocchi
'dumplings?' is the definition.
(I've seen this before)
'george cooked cochin' is the wordplay.
'george' becomes 'g'.
'cooked' indicates anagramming the letters (letters cooked into a new form).
'cochin' anagrammed gives 'nocchi'.
'g'+'nocchi'='GNOCCHI'
(Other definitions for gnocchi that I've seen before include "Dough" , "that is eaten" , "A course in Rome" , "Italian dumpling made of potato, flour or semolina" , "Italian potato dumplings" .)
