Dish - English sweetheart in spin (6)
I believe the answer is:
tureen
'dish' is the definition.
(tureen is a kind of dish)
'english sweetheart in spin' is the wordplay.
'english' becomes 'e' (abbreviation).
'sweetheart' becomes 'e' (the heart/centre of 'sweet').
'in' is an insertion indicator.
'spin' becomes 'turn' (I've seen this before**).
'e'+'e'='ee'
'ee' going into 'turn' is 'TUREEN'.
(Other definitions for tureen that I've seen before include "A deep covered dish for serving soup" , "Soup container" , "Soup-dish" , "Deep bowl for serving soup" , "wooden dish" .)
