Editor enthralled by Greek cooking eastern rice dish (8)
I believe the answer is:
kedgeree
'rice dish' is the definition.
(I've seen this before)
'editor enthralled by greek cooking eastern' is the wordplay.
'editor' becomes 'ed'.
'enthralled by' is an insertion indicator ('enthral' can mean 'capture').
'cooking' indicates anagramming the letters (cook can mean to falsify or distort).
'eastern' becomes 'e'.
'greek' anagrammed gives 'kgere'.
'ed' inserted inside 'kgere' is 'kedgere'.
'kedgere'+'e'='KEDGEREE'
(Other definitions for kedgeree that I've seen before include "fishy meal" , "Fishy breakfast dish" , "Fish/rice/egg dish" , "Rice, fish and egg dish" , "Dish of rice, hard-boiled eggs and cooked flaked fish" .)
