Apple coating (7)
I believe the answer is:
caramel
'apple coating' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for caramel that I've seen before include "Soft sweet" , "Browned syrup" , "Shade" , "It's produced by heating sugar until brown" , "Chewy sweet - burnt sugar" .)
