Sample ultra-romantic fragrance (5)
I believe the answer is:
aroma
'fragrance' is the definition.
(synonyms)
'sample ultra-romantic' is the wordplay.
'sample' says the answer is hidden in the clue (I've seen this in other clues).
'AROMA' is hidden in the letters of 'ultra romantic'.
(Other definitions for aroma that I've seen before include "Perfume" , "Agreeable odour" , "Spicy fragrance" , "Savour" , "Redolence" .)
