Fireside drink (5)
I believe the answer is:
cocoa
'fireside drink' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cocoa that I've seen before include "It's made from the seed of the cacao tree" , "Light brown" , "Hot chocolate drink" , "Popular chocolate drink" , "Powdered cacao seeds" .)
