Spirited trumpet piece (3)
I believe the answer is:
rum
'spirited trumpet piece' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'spirited trumpet piece' is the wordplay.
'piece' says the answer is hidden in the clue.
'RUM' is hidden in the letters of 'spirited trumpet'.
Can you help me to learn more?
(Other definitions for rum that I've seen before include "Odd sort of spirit used in grog" , "Queer" , "Odd sort of drink" , "An alcoholic spirit - sounds odd" , "An odd kind of drink made from molasses" .)
