Savory taste (5)
I believe the answer is:
umami
'savory taste' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for umami that I've seen before include "Savoury taste sensation produced by glutamates - I, a mum (anag)" , "Newly discovered taste" , "acquired taste perhaps" , "Fifth flavour" , "Japanese word for pleasant savoury taste" .)
