Save the chocolate (3)
I believe the answer is:
bar
This clue is a double definition.
'save' is the first definition.
(I've seen this before)
'chocolate' is the second definition.
(I know that bar is a type of chocolate candy)
'the' acts as a link.
(Other definitions for bar that I've seen before include "Sandbank; barrier" , "Watering hole" , "Impediment" , "sovereign" , "Stop" .)
