Polish relish? (5)
I believe the answer is:
taste
I believe this is a double definition.
'polish' is the first definition.
(thesaurus)
'relish?' is the second definition.
(relish is a kind of taste)
(Other definitions for taste that I've seen before include "Little bit" , "Test for flavour" , "To eat sparingly" , "Savour in state" , "Perceive the flavour" .)
