Perfume discovered in Emilia-Romagna (5)
I believe the answer is:
aroma
'perfume' is the definition.
('aroma' can be a synonym of 'perfume')
'discovered in emilia-romagna' is the wordplay.
'discovered' says the answer is hidden in the clue (remove the letters covering the answer in the clue).
'AROMA' can be found hidden inside 'in emilia romagna'.
(Other definitions for aroma that I've seen before include "A pleasant smell as of food" , "Distinctive odour" , "Savour" , "Bouquet" , "Agreeable odour" .)
