Burn chunk of peat or charcoal (5)

Ross

I believe the answer is:

torch

'burn' is the definition.
(torching is a kind of burning)

'chunk of peat or charcoal' is the wordplay.
'chunk of' indicates a hidden word.
'TORCH' can be found hidden inside 'peat or charcoal'.

(Other definitions for torch that I've seen before include "Link" , "Set fire to - hand-held light" , "may get one glowing" , "Source of light" , "Flashlight" .)

I've seen this clue in The Times.
