Pan, and what may be in it? (5)
I believe the answer is:
roast
'pan' is the definition.
(both can mean to criticise)
I don't understand how the rest of the clue works.
(Other definitions for roast that I've seen before include "Carpet" , "Cooked like chestnuts tonight" , "Cook (meat) over a fire" , "Give a telling off to - cook" , "Criticise severely" .)
