Meat product in mail as ordered (6)
I believe the answer is:
salami
'meat product' is the definition.
(I know that salami is a type of cold cut)
'mail as ordered' is the wordplay.
'ordered' indicates anagramming the letters.
'mail'+'as'='mailas'
'mailas' with letters rearranged gives 'SALAMI'.
'in' acts as a link.
(Other definitions for salami that I've seen before include "Food" , "Hooked" , "Garlic- flavoured sausage" , "Cured meat" , "Italian garlic sausage" .)
