I believe the answer is:

ashes

I'm a little stuck... Click here to teach me more about this clue!

'trophy' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for ashes that I've seen before include "Powders remaining after fire" , "Eng./Aus. cricket trophy" , "Burnt residue" , "International competition" , "Remains from a cremation" .)

I've seen this clue in The Guardian.
