Type of vinegar (8)
I believe the answer is:
'type of vinegar' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for balsamic that I've seen before include "Italian type of vinegar" , "smelling of perfume" , "Concerned with healing" , "BAs claim this strange type of vinegar" , "Variety of vinegar" .)
