Bread sauce (5)
I believe the answer is:
brass
I believe this is a double definition.
'bread' is the first definition.
(thesaurus)
'sauce' is the second definition.
(thesaurus)
(Other definitions for brass that I've seen before include "Nerve (but not of steel!)" , "impudence" , "Boldness" , "some musicians!" , "neck" .)
