Cold cut and sweet perhaps (4)
I believe the answer is:
chew
'sweet perhaps' is the definition.
(chew can mean a sweet which is chewed)
'cold cut' is the wordplay.
'cold' becomes 'c' (eg on taps).
'cut' becomes 'hew' (hew can mean to chop or cut).
'c'+'hew'='CHEW'
'and' is the link.
(Other definitions for chew that I've seen before include "work with canines" , "Prepare to swallow" , "What gossips do to fat" , "Gnaw" , "Treat for dog" .)
