Cook in pan (5)
I believe the answer is:
roast
This clue is a double definition.
'cook' is the first definition.
(I know that roast is a kind of cook)
'pan' is the second definition.
(both can mean to criticise)
'in' is the link.
(Other definitions for roast that I've seen before include "Slate" , "Oven joint" , "One way to cook meat" , "Grill" , "Have a go at" .)
