Experts to include one into chopped ham (10)
I believe the answer is:
prosciutto
'ham' is the definition.
(I've seen this before)
'experts to include one into chopped' is the wordplay.
'experts' becomes 'pros' (I've seen this in other clues).
'to' becomes 'cutto' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'include' indicates putting letters inside.
'one into' becomes 'in'.
'chopped' means to remove the last letter.
'in' with its final letter taken off is 'i'.
'cutto' placed around 'i' is 'ciutto'.
'pros'+'ciutto'='PROSCIUTTO'
(Other definitions for prosciutto that I've seen before include "Meat" , "sliced delicacy" , "Raw cured Italian ham" , "Italian food" .)
