Syrup from maple perhaps covering a caramel's edges (7)
I believe the answer is:
treacle
'syrup' is the definition.
(I know that treacle is a type of syrup)
'maple perhaps covering a caramel's edges' is the wordplay.
'maple perhaps' becomes 'tree' (maple is a type of tree).
'covering' indicates putting letters inside.
'edges' says to hollow out the word (remove centre letters) (I've seen 'edges of' mean this).
'caramel' with its centre taken out is 'cl'.
'a'+'cl'='acl'
'tree' going around 'acl' is 'TREACLE'.
'from' is the link.
(Other definitions for treacle that I've seen before include "Carroll's sisters had to live with" , "cloying stuff" , "Golden syrup" , "refined product" , "Thick syrup from sugar cane" .)
