Caramel (6)

I believe the answer is:
toffee
'caramel' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for toffee that I've seen before include "Chewy confection" , "Confectionery made from sugar and butter" , "can we not do something for it?" , "That could be tough to swallow" , "Chewy stuff" .)
