Dessert with essence of honey (10)
I believe the answer is:
sweetheart
'honey' is the definition.
(I've seen this in another clue)
'dessert with essence' is the wordplay.
'dessert' becomes 'sweet' (synonyms).
'with' means one lot of letters go next to another.
'essence' becomes 'heart' (synonyms).
'sweet'+'heart'='SWEETHEART'
'of' is the link.
(Other definitions for sweetheart that I've seen before include "Term of endearment" , "flame?" , "Love" , "baby" , "Lover" .)
