Cooked chestnuts (7)
I believe the answer is:
roasted
'cooked chestnuts' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for roasted that I've seen before include "Severely reprimanded" , "Cooked (turkey?)" , "How meat might be cooked" , "Cooked hot food" , "Carpeted" .)
